Very solid start for your first 3D game! The character design is excellent and I liked a lot of what you were going for. The dash into long jump into wall slide is reliably very fun.
I think I had a lot of similar issues to other folks, just some general 3D polish that I won't bother to repeat. My biggest issue was just the "wall state" and ledge grab not triggering consistently. This may be an issue with the level geometry, not sure. And a few more sound effect would have gone a long way: jump, land, wall grab, and wall sliding would have given some nice feedback to make everything feel better. Hope yall keep working on this!!
