Nice game!
Right click Meow came in clutch.
I made it really far and didn't die but I think that might be due to all my monsters being stacked on top of each other.
I pretty much had a full invincible bar most of the time and I didn't even notice it ticking down until around wave 25 and then looked at the instructions as wasn't sure if I'd die when it ran out or what was happening to it.
I liked the game, it was a bit laggy when the portal came but that was ok as all the monsters are gone by then any way.
Good Job and good luck in the Jam
