VERSUS BULLET HELL

It's Undertale but you play against each other, and there are 6 characters to choose from.

Touch orbs and pick a direction to send an attack to your opponent

Getting hit causes the struggle bar to move towards your side, if it hits the end. You lose the round. If time runs out and its on your side, then you still lose. 

Player 1 uses WASD to move, and L-SHIFT to activate orbs and L-ALT to use specials

Player 2 uses IJKL to move, and SPACE to activate orbs and ; to use specials

Alternatively, if you connect a controller, Player2 can use a controller. DPad to move, and X to use your orbs, O to use specials
