I'm liking it so far! If I could suggest a couple of small improvements:
It's sometimes difficult to wall jump because if you press away from the wall, you immediately move off of it, and can't jump. I'd suggest implementing a feature where holding away from the wall doesn't immediately detach the player, but instead waits like 10 frames or so. Most popular platformers with wall jumping do this, and it makes wall jumping feel a lot more responsive.
Being able to move with the arrow keys would be nice too, should be an easy thing to implement.
Other than that I really enjoy it! Sliding feels super great and the levels are challenging! Going to keep an eye out for further development updates (Came here from r/godot)
