Congrats on completing!
I really liked not having the left arrow in the first level! Some jumps felt impossible without taking damage, but I probably just suck :D
I did play for quite a bit and found it fun to keep trying, if the movement was a bit more tweaked I would like it even more.
I also got stuck at the end of level 1 for a bit because I overshot the goal (I did a mega jump of the stairs as I would In Mario)
