Thank you for the feedback. I found the glitch, but since game jam voting is happening, i cannot re-upload it (which makes me quite annoyed).
As for the walljump, I've been trying to make it better, but this is the best I came up with. Fortunatelly after level 2 there is not much more of it. :D
If u liked the game, there is still a lot more mechanics and a boss too. I'm gonna upload the working version in 2 weeks, so feel free to finnish playing it. :D
