The exclamation marks are a bit of a visual tutorial pointing out important or dangerous things. The main reason for their existence is that they existed tho! I have some other signs which simply didn't make it into the game yet :D
Yeah, walljump was intended to be used where double jump is not enough. In the end wall jump is quite easy, a bit to easy...but it could be harder later on with spikes at the walls or so.
My first sidescroller in Godot. Yeah, the physics do their sometimes. I'm okay with the result for now x)
I had a jetpack on w in my version, that is mostly why not just space for jump, more like moba conrols hehe
The UI would be an idea, ofc time expensive q.q
Friction gotta be done! SFX are a time question ofc, so is music.
Finishing the game without climbing isn't that easy! some levels can be annoying that way o.o
