Thanks for playing, and all the great feedback! I'll admit, getting the wall kick to a point where I was happy with it was tough. I initially tried the setup you suggested, using the directional key in the direction that you want to wall jump, but it felt worse that the default setup. I checked some other games while struggling with this (Celeste and Celeste classic in particular, as they were my main inspirations) and settled with no directional keys... you auto wall jump if you press jump while close enough.(Pressing toward a wall certainly helps with this though) If I were to make a "full" game out of this, it's definitely something I'd explore tweaking, as I agree it's not perfect.
Hitboxes will definitely be getting a second look when I have time for an update. I'm glad the tons of respawn points were helpful. I certainly expected/intended for first run players to use them a lot.
I'm also glad you enjoyed volume of content, because I don't recommend it for a jam haha.... it was pretty stressful, especially toward the end when I felt seriously committed to completing the full game. (And then immediately started planning a "Secret" stage 7&8 I'll be adding post jam, lol)
Thanks again for your detailed feedback, and sticking it through to the end! I'll keep all of this in mind when I work on the post-jam updates!
