It's a platformer, so the feedback may feel quite obvious...
- The jump mechanic feels floaty and a bit weird (maybe you intended it like this, but I can't really tell from the game)
- Hitboxes for the "Q" ability feel weird (you stop a few meters before the obstacle and get stuck, the ability itself can be used only on this stuck range)
- If I didn't read your comment about the theme, I wouldn't tell it's connected
Anyway, it's a great start!
