Very fun game to play! The character won't jump correctly if you press D and jump at the same time. (its caught between the character's collision). Very nice project!.
I left in the ability to Shimmy up walls (by pressing D and jumping up the walls), but i'm not sure if this is the same issue you're refering to.
Either way I need to make a firmer decition on the jump mechanic and lean into it one way or the other.
Thanks for playing, glad you found it fun!
