With the arrow keys as the control, it would be helpful if the replay/next level could also be selected with the arrow keys; it's a bit annoying to have to switch back and forth from keyboard to mouse.
The learning curve can be kinda brutal - that second level is pretty harsh. A projected shot line on the first few stages would be nice. Have you considered ye ol' unlock levels, choose you level system? Oh, and it should be 'prove' rather than 'proof'. All and all, though, a fun little game.
thank you for your criticism. i think i should change the level order. your not the first who think that the 2. level is to hard. its pretty interesting to get some feedback. if you are working on it, you lose this gamer point of view...
