The game is very challenging, but also very interesting. All the effects are really well done, and the visuals overall are top-notch. Great work!
(And the visuals remind me of my own game, which is funny!)
The idea of jumping and falling with the spacebar is really good. Also, the concept of trampolines on the top side of blocks is cool. But I didn't quite like the laser—it's hard to notice, and you don't have time to react or understand when it's going to shoot. The laser's charge-up should be more noticeable. Otherwise, everything is great!
