Interesting.
Interesting concept but you made many mistakes throughout development...
When you "freeze" something you expect it to be harmless, i understand spikes still killing you ..but bullets ? They no longer have their momentum and should be just little lead pellets, instead they kill you on touch
Exit is like a reward... you have done your job well and you may now proceed to next level.. so please.. add boundaries of the level.. because falling off the ledge just next to the exit is something that players really don't like.
More sounds. When you shoot your.. time-thingy-gun it doesn't make a sound at all, and sphere "explosion" sound is extremelly awful. There is no sound to anything else like jumping, landing on ground beside that and dying..
Cheers.
