So a lot of time spent already on building up a good set of supporting code. Grrr, I never ever learn. But I'm getting faster at it or may be it's just me and lua.

But we have placement of spitball launching circles (should be heads eventually). We also have cats randomly appearing with health and being fired upon by the heads you've placed. Yeah! Pretty much the tower defense core mechanic.

You can get the build at itch.
