I tried it out and it is awesome! I congratulate you for the heard work, I like how you can flip gravity. If turn this into a full game, that'd be EPIC!!! One thing though, if you look closely at the "Fighter Bot" sprite, there are little random pixels around it.
just downloaded again and all the files and tiles with the word megaman in it couldnt be found. my suggestion for an re-upload would be to just rename your files fighterbot or FB instead of megaman. idk if that solve the missing sprites but would love to try your game after reading that huge thread on reddit thx!
