I really like this game, but...
1) I don't know, maybe it's just me and my outdated software, but starting from level 5 it lags terribly, and often game becomes totally unplayable.
2) Not enough time orbs. And why can't I have more than 2:30 of time? It's really frustrating, at first level time orbs just go to waste, and on next levels you just run out of time.
3) Why it's dark near the door, but there is more light farther away from the door? If it was the reverse way, it would make sense: there is a source of light near the door, but the farther you get from the door, the darker it gets. Darker means more dangerous (not the danger of enemies, but the danger that you'll not return to the door).
4) What do switches even do?
I like your works, hoke you won't stop making games.
