Very solid game! It's simple with not much to it, unfortunately, but what's there felt very polished and satisfying to play! Just running around and slamming the disks into the portal was quite fun thanks to the fluid animation, and I found myself easily getting addicted to it. Interesting design decision to offset the annoyance of the level up ability pop-up by giving the player invincibility during. It's all well and good, my only real complaint would be that I don't like how fast it respawns you after death: I would prefer that it sit at the death screen with your corpse for a bit more to wait for you to confirm with another button press when you want to restart. Nice job on this, as I love some solid arcade fun!
