It was quite fun to play through this game :)
I think with some further improvements it can get a nice small speed run challenge (like stated in the description on the itch page). Would be cool if you integrate a timer and maybe a high score/leaderboard. The game ended in an empty level (at least for me). If that is not a bug, it would be nice to have a game over screen or something like that.
I liked the mechanic of replaying the same level with increasing difficulty and the introduction new challenges over time like double jump, the limited field of view.
