If it was fun, then it's feature. But yeah, i bet there a lot of bug. Thanks for review :)
genuinely, you should keep it as a feature. Maybe make some little ridges and ladder things for the player to climb up to get to higher places! I do think the bug in general might need to be fixed to prevent levels from being too easy, but it should definitely remain in some way or another. This game is totally going places and I really hope you continue it in the future!
