This is a REALLY cool game and I actually love playing. I would keep going but…. A couple issues the void sometimes kills you right at the beginning of the game. You need to work on getting that to be more reasonable. Sometimes you’ll be in a void that is basically a lake and there is no way to escape. In order to leverage strategy, there needs to be at least 1 safe place to move every 2 changes of the void (given its change speed). Also, I think changing the void a bit slower will still make the game fun. Getting that timing and ensuring the user understands it is critical, I think. Minus one point for this miss-timing and another for killing a player right at the start due to a bad void.
The game glitches out when the joystick is connected. Much better however w/ the music and sound effect! The arcade action of this game is only extra steps. You are are just about there.
I really think this is an interesting game, and you can go much further w/ this concept.
