Nice Short Hack! I really enjoyed the castle, and overall it was fun.
But there are still flaws, i want to address a few:
1. In the first level, the platforms you are supposed to land on after getting shot from a slanted pipe are too short, i took me a few attempts to make it, but was annoying.
2. After getting the secret exit in the second level, the Yoshi's house exploded, i know this is a small issue but it would be nice to fix it.
3. When beating a level, the event tiles were in very strange positions (Talking about the castle)
I dont want to discourage you from making rom hacks in the future.
I just had some issues i wanted to address.
I support everyone on this site making hacks, but if you have any problems with events and level exits you should take a look at DanOfMostTrades on youtube, or take a look at the help section on this site.
Most Love, S1Z2
Pretty Short & Standard Hack like the name of it gives away.
Nothing really to say other than its a fine little adventure with an updated version coming soon including World 2.
If its your type of SMW hack then you'll enjoy it.
I will say though some variation of sprites or background changes could make the levels stand out more from whats available in the original game but either way its a good romp.
