A very beautiful game, love the graphics :)
Gameplay is quite fun, I just can't figure out how to finish levels: even when all chests are open and all robots are left, I'm stuck on the screen... So I press Q to go to next level, but it feels a bit wrong.
Some locked doors are in interesting places, I wonder if you planned to hide a key somewhere in levels to add a bonus challenge?
Very cool game anyway :)
