WASD - move E - throw a smudge Throw smudges at appearing holes so they disappear. On the left there is a wave counter, there are 3 waves and the 3rd is infinite. There is also a wave progress. On the right is your health. If it turns 0, it's game over.
I'm still gonna add some things to this, like main menu and appearing upgrades, but you can suggest me ideas.
