Although it's short, what you have so far is very nice and extremely polished. If nobody else wants to tackle it, I can give it a shot (I have a bit of experience designing levels in this style if my recent YI contest level is anything to go off of).
I've actually finished off the section Wuthering already designed (half of the level) and made a pipe exit to this portion. I was looking for a brighter color set for the FG, but this is the only decent palette I could find that didn't cause glitchy colors on the log tiles.
Would it be possible to do a precise flutter jump through the Wild Piranhas and avoid using an egg entirely?
You'd have to be pretty spectacular to pull it off I think.
The first time I entered this room, the Goonie spawned too low, giving me little time to react before being attacked by it. Lowering the height of the pipe by one tile would fix this
I found this part very annoying to get through.
Also, I'm not sure if it's because I'm bad at YI, but I found the second-to-last room overly difficult compared to the rest of the level. It would benefit if you could add more places to rest in between all the Goonie riding.
Is it okay to still submit an update on this? I was playing through the level for the first time in a while, and while I think it's nice through the most part, there are a couple things I want to change. My biggest issue is with the room where you have to hop on Goonies across mass stretches of pits. I still stand by me saying that it is just way too hard, especially when compared to rest of the level. Not sure how I even beat it the first time.
I'll send S.N.N. a PM seeing if this okay with him, since he's the one who designed the segment.
