Thanks for the feedback! I do want to fix the frustrating wall issues, and my team is planning on supporting this game after the jam so we should be able to fix it soon.
My current plan for the fix is to add some areas that will help nudge the player in helpful directions if they are currently colliding, but I will look into the move and slide method also. The movement in your game felt buttery smooth so maybe a mix between the two will hit a sweet spot!
