I reached this level/part/round, destroy all the enemies, and ended up with this....
And nothing else happens, so... technically , reached the end?
The game is well designed and the "push the enemies to the walls" mechanics is pretty cool, although kind of complicated with the grid movement system of the player. Maybe with a "press: moves, release: stops" movement would be more fun. I had a really hard time making them crash into the upper or lower walls, because of the control system. Ended up killing them with the spikes.
The graphics are really nice with lots of visual fx.
Great job! Congratulations!
