Hi! I beat the third wave, but the achievement didn't pop up. It's a pity, it's the only one left! Nice game overall, I'm having fun.

Looking forward to play the game! Has the game background or story?

I like to think that these creatures are the result of the infection of human corpses by the cells of a lovecraftian being. Like necromorphs from Dead Space.

I have killed all the required enemies, but neither the new skill, nor the new weapon unlocks. When I try to see how many enemies I still need to kill to unlock the next level, it says -83. This is a huge bug! It really needs to be fixed!
