Game is crazy hard. I never got passed the "raffle ticket" door!?! And I assume that's the tutorial. Been playing for many hours and it's frustrating. There are no hints, no guide by level design, and the controls are Janky.
Gun play - terrible
Ability to move or jump - nausea
Trying to climb - so impossible, constant glitch.
Physics environment - good
Overall, not at all worth buying.
