Woah another 10/10 game. This game is really really good, good gameplay, good graphics, good musics, good colours, its all good. This game remind me alot of a game i used to play on my phone that had ALOT of levels, like 999+ levels (https://play.google.com/store/apps/details?id=com.balysv.loop).
This game could be like that, you can just add alot of levels, you could even make a level builder. I like games that dont have a lose condition, its just you and the puzzle, take your time. Also it was made on pico 8, i love me some pico8 stuff.
