WASD/ARROW KEYS to move. Space to change type. Black is normal, blue is slow but high-damage, green is fast but low damage. At 100 score, you get a second, continuous attack. Be warned this could potentially lag less powerful machines due to a large amount of sprites (pretty much only applies to cheap chromebooks).
don't die it's kind of hypocritical to post this right after an inactivity notice but i'm pretty much just posting everything i have now. maybe i'll continue working on this? dunno.
