So... apparently to defeat the darkness, you need to collect the purple disruptors. I assume it of course, because you didn't arse yourself to bother to write it anywhere or shit. Thing is, it could have been a nice little game with cool concept if not for one problem... Every time you take the disruptor (or not), the game lags moar... albeit it also becomes easier. After taking like 3, it basically becomes an empty space with black blob not moving anywhere, and the walls occasionally still trying to kill you.
Maybe finishing the game is possible, but you will probably need few hours to spent looking at the game, or maybe even longer (Maybe a full day?).
The most baffling thing about it all, is that this game was allowed to have medals.
I must admit that's some pretty good standards for people who approve this kind of stuff to have, I say, to let the medals for the game that is unfinished and very buggy. Good job I guess.
