Lot of stuff in this game and unfortunately it was all just throw at you in the tutorial and information screen. Also the keys were not placed very well - WASD and then CVB? spread out the two hands on the keyboard.
I really wanted to play through and beat the game but things like reverse gravity not being able to turn off and the slow slow pace of game really did not help.
The hit detection boxes of the character and the enemies also needs some work.
Sorry for ranting this is because I think you have a great start here - just need to find a way to bring it all together and work out the bugs.
Thanks for submitting - would love to play a fixed up version.
