The joysticks make no sense, except that I know they are there because it's a default thing in UE4. Ideally in a phone game you would just tap in a part of the screen to go that way and since this game only has two directions to go to seems like an easy thing to do. Also for some reason you can crouch which idk if makes an effect on the game since collisions don't work and you can also jump but only on keyboard.
Jumping doesn't make a lot of sense to me but I think it would be fun if you could like change gravity VVVVVV style instead.
Visuals are horrible and I guess they're mostly placeholders but I would rather look at plain colors.
Obstacles don't work but the annoying thing about them is that they get in the way of the camera, work on a shader that hides them after passing them by.
Camera is very wonky, consider adding a spring arm with a bit of lag speed.
Overall feels like something made over half a weekend.
