Cute little game, I really liked the voice lines. Being a bit influenced by Parable of the Polygons, I do have to wonder why my triangle doesn't want to make friends with non-polygons, though (not to be taken too seriously).
I do have some issues when I run the game longer than a few minutes that it first starts to lag pretty badly and eventually crashes. My PC is relatively low-end, but this game feels simple enough that it should be able to handle it. Maybe you should look into your code and see if you have some sort of memory leak or something? Maybe I just need a new computer, though.
