This is pretty nice for a game thats made just to learn an engine. I completed all of the levels! Graphics are alright. the sound is ok, though i think the shoe squeaking might get a bit irritating for some people (i was alright with it but still). Levels are somewhat alright, you could potentially place some little arrows that tell you where to go but i was able to more or less navigate all of them. The controls are a bit odd to me, i think that to jump from a wall you should press the button again instead of being able to hold it as it can mess up walljumps when jumping close to the ground, and also i think that its unnecessary to double tap the fast fall button for it to actually work, and also allowing to fast fall while clinging to a wall would be very nice. Potentially making the roll more similiar to something like sonic the hedgehod where you can crouch down for a second to charge it up without moving or jumping would be good, though might just be me. Adding some more visual and audio effects would be quite nice, like when you roll, get the last target or die, also i feel like adding background music would be good, im sure that if you ask someone nicely on the music portal they could allow you to use their music in the game, or hell, maybe even compose a track yourself. Overall this is a pretty nice beginner project. Good job!
