Thank you for playing the game and for the great feedback!
At wave 10 the camubugs spawn which can only be killed by stray AOE damage or the flower tower that can see camouflage. The game is an endless game and the waves get stronger at lvl 25 and 50, though it has not been balanced for more than 15 minutes of gameplay since we didn't expect players to stick around for longer haha. Thank you for hanging around for more than 10 runs <3
Adding bosses every couple of waves is definitely something we'd love to do, so maybe if we have time we will after the jam!
