Wow, pretty cool game, simple but efective mecanics. I saw that the wallrun was clunky but it was probably hard to code tho... what you probably did was something like "If both W and D where on the right wall, then wallrun"... you could have done something that conditions more on the collision while moving instead of a constant check of buttons, also sometimes when i stopped pressing one of the buttons i was still on the wallrun, but i coud't move...
But then again, the game is challenging while not being punishing, so it has a good over all desing, except for the weird ball on one of the levels, and the theme of the gamejam in this game i would say its kinda lazy. In conclusion, good game, cool desing, good mecanics.
Congrats man
