I really like this hack.
First level was amazing, and pretty challenging too. All other levels are great, too. Cutscenes are funny, and aesthetics are outstanding. I did find a few issues:
-For some reason i managed to create garbage sprites in this area. I thought it might be lag, though it doesn't occure in other laggy areas (1-4). Some of it stays in background but gets fixed once another level's entered.
-As expected, with limited cluster sprite OAM some tiles may disappear. Also, i find that area a bit too chaotic, despite being short it's pretty difficult.
Overall, this is a really good hack, with a lot of polish and care. Aesthetics are nice and level design is solid. Defenitely looking forward for this one. 9/10. Keep it up
(also, how do you enter 1-B? i can't reach it, unless that's intentional)
