About 1 and a half hours.
Did I have fun?:
I did have fun most of the time.
I will only judge the levels seeing as this is the first beta. The overworld is really bland and odd looking, but I can forgive it if it gets better with newer Betas. Nancy looks fairly good, but her P Balloon form is really awkward and also kinda glitchy like mentioned above.
Graphics: Basic. Really basic. I mean, nothing is new here. The palettes are alright in the first half, but the second half is kinda ugly. No points awarded.
Music: Sounds alright, but it's really unfitting with the atmosphere of the level. Half a point awarded.
Gameplay: Really bland at some points, but enjoyable at others. The first half feels somewhat uninspired at some points, but the second half makes up for it with its fun level design. Half a point awarded.
Extra points: The gimmick in the second half with the upside down Thwimps is pretty well done. Half a point awarded.
(Note: You can get stuck and die in a hole in a wall right after entering the pipe to the second part)
Graphics: The FG is okay, the BG unfitting to what the level is about AND the palette of the FG. Doesn't mean it looks bad, just kinda off. The pipe-as-a-minecart thing is kinda weird but it is functional enough. No points awarded.
Music: The same as in Mt Thwimp, but even more unfitting, somehow. No points awarded.
Gameplay: Looks like it's just thrown together to test stuff, especially at the end. Not very enjoyable. No points awarded.
Extra points: To give credits where it's due, the minecart itself works quite well. Half a point awarded.
(Note: The jump sound is very distorted sometimes)
Top Secret Area
I'm not gonna give this one a grading because it's not a real level, but I did like the little secret you can get to if you use wings. The wings are pretty cool as well, if a bit too OP for regular levels. Luckily it fades after you exit a level.
Graphics: The balloons look sweet, the castle tileset fits suprisingly well with the forest background in the first half and the second half doesn't look to shabby as well. Point awarded.
Music: Yeah, sorry, but it's still unfitting, especially in the later half. No points awarded.
Gameplay: The Tubular part isn't enjoyable because there's no way of telling that there's a whole level beneath. For the rest, it's a very well designed level. Sometimes you have to wait a bit too long for the next area, but that's not much of a problem if you can fast forward. The final part is really enjoyable if a bit short. Those are all minor nitpicks though, this is my favorite level overall. Point awarded.
Extra points: Absolutely. The balloons work really well, especially the ones in the second part. Point awarded.
Graphics: I don't know why everyone's complaining about the palettes. They're solid if unspectacular in my book. Half a point awarded.
Music: Basic SMW, but at least it's fitting this time. Half a point awarded.
Gameplay: Not a particularly special level, but still quite fun to play through. Half a point awarded.
Extra points: This level is just a little too non-gimmicky compared to the others. No points awarded.
When In Doubt...
Graphics: The first half has an ugly foreground. The second half is quite good. Half a point awarded.
Music: The beginning had me fearing for the worst, but later on in the song it got a bit better. Not groundbreaking but it'll do. Half a point awarded.
Gameplay: This level has a boatload of good ideas, but the first half was quite dull. The second half was really neat though. Half a point awarded.
Extra points: The gimmick of the second half was really nice and was used properly. I don't know about the first half though. Was there even much of a gimmick? I don't understand the title either. Half a point awarded.
2/4 (Very Good)
Graphics: Could've been much more lakeside-y, but that doesn't mean they're bad. The palletes are a joy to look at. Half a point awarded.
Music: Nice music and could've fit well if the graphics corresponded to the lakeside theme. Half a point awarded.
Gameplay: It's just not really well made. I get the ideas and they are good on paper, but persoanlly I didn't enjoy it much. Too many jumps that are questionable and too many Spinies thrown together. No points awarded.
Extra points: The ideas were good, just not executed well enough to really rock it. Half a point awarded because I think it still deserves credit.
Graphics: Not much to say other than that it is respectably good. Not special but it works like it should. Half a point awarded.
Music: Again, the more you repeat the same thing, the less enjoyable and fitting it becomes. No points awarded.
Gameplay: This level is honestly much too aggrevating for these kind of hacks, because the screen scroll doesn't work how it should (the objects off screen still work but reset if you return, causing some weird situations). It also has too many precise jumps and climbs. No points awarded.
Extra points: The idea is good enough but it just didn't come out well. Half a point awarded.
Graphics: Is it just me, or does just about every FG tileset work with a forest BG? Anyway, while that looks fine, the enemies walking on lava look awkward and the glass-like blocks in the second half are weird. No points awarded.
Music: This music piece fits the level MUCH more than the others did. It doesn't sound mightily impressive on it's own though. Half a point awarded.
Gameplay: This level has some good ideas, but some choices are questionable. In the first half it seems you ran out of ideas with what you got and just added different kinds of enemies and blocks to see how they would respond to lava. Overall though, I still enjoyed playing through it. Half a point awarded.
Extra points: The ideas were quite something. While a few didn't EXACTLY work, the second half was awesome. Playing 'the floor is lava' in the first level in SMB already a fun challenge, but now it got serious, and that feels great. It's full of good ideas and that made this a solid level. Point awarded.
14.5/28 or 5.2/10 (Good)
Despite the low rating, I did really enjoy myself and had quite some fun doing this for the review. The music choice is poor and the design seems mixed & mashed together in some levels. Still though, you have a good hack in your hands. Be a bit more creative with your music and focus on a gimmick at a time untill it seems like you can't do much more with it, then change it correspondedly.
Hope this has helped with the further design of this hack and future ones as well!
