Please forgive my initial, slightly frustrated message; just a couple of points:
- I didn't know there was a double jump; the game doesn't mention it.
- I didn't realize a timer was running because the UI doesn't show it unless you're in full-screen mode (I couldn't figure out why I kept getting a "game over").
- There’s no sound cue when I pick up items, and I often miss them because the collision box is very small. Otherwise, it’s a nice concept and actually challenging once you grasp the basics.
