I really like the game idea, it's straightforward and fun!
I also see that you can take multiple path choices on some rooms and I think it would be nice to see even more of that.
I like that there are enemies as well, but I don't really get the point of defeating them because they don't reward you with anything and also make you slow down to get the kill, so I kinda just jumped over everytime, which is a shame because they are very cool to kill while running. Maybe making them give something (like points?) and maybe making the knockback stronger so that you don't have to slow down? I think they could add a new layer to the game if you were motivated to not ignore them.
I did find a glitch where if you start jumping right at the beginning before touching the ground for the first time, you can spam jump forever and fly lol.
