Great game dude, love the running and it feels good to just move around the game.
The wall running and wall jumping does need a little bit of work, it just doesn't feel good to me, Ill try to explain why if you need me to, but it just doesn't have that weight or something.
Coins that have more value should also have more than just a Blue outline.
Maybe make bronze coins the regular ones and gold coins have more value? idk, all up to you.
