so far I played three levels of your game and here's what I think :
the game has good visuals and aesthetics even though the music for the first level interrupted me to focus on the story
the character is totally underdeveloped it lacks the flow of mouvement and the jump is really difficult to control and doesn't allow for the one frame ahead jump for example if I press the space bar one second later he doesn't jump especially given how difficult the level design is
speaking of that the difficulty in the game looks pretty randow and accelerated like I just started playing and like less than 5 minutes later the game is already difficuly as hell
I would like to see some more improvemnts especially in the character and level design
Good luck man hope I see better content from you in the near future
