Nice for a 48 hour jam. :)
Two improvement points:
- The text. It was sometimes hard to see what text said with it being white and the background also being white sometimes. Also a bit hard to to look at the small letter at the top of the screen while the obstacles or "targets" are on the bottom side.
- There is no punishment when pressing space and "missing" a target. One could buttonmash the space-button without any punishment.
