This game sucks:
1. No saving;
2. Horrible lag;
3. Controls are terribly glitched;
4. As mentioned: there are lots of moments when you cannot return to fire ability;
5. Eventually the game just froze and even caused the browser to stop working.
And the author did not bother to fix anything.

Dragging those boxes is a pain. They get stuck on invisible walls and failing to be placed on the spots. For some dumb reason you sometimes cannot move them at all upwards or to the right.

I agree that the idea is interesting, but... the whole randomness discourages from playing the game further. I am also 100% sure that nobody will ever get the last medal, it is just impossible. Also one crucial thing: having in mind how long it has to take to finish the whole game PROGRESS SAVING is ABSOLUTELY NECESSARY. It is also related to the medal issues people may experience: the game will simply disconnect from NG after such a long gameplay and the medals will not be awarded.
