Thank you very much!
I know that those 2 sounds are a bit odd, I already noted to replace them :) I learnt about the Pixel Perfect camera in Unity which should take care of the horizontal lines, I'll update the game after the jam. As for the Z order I just couldn't decide how to solve the issue so I put everything to be obscuring the player but of course I'll do something about it, now that I have more time :D
Thanks for playing and thanks for the feedback!
