So far seems good! I found that whilst the game is playing, there is now way to leave without quiting the app. Maybe try to add a pause screen? The music in the background gets a little anoying after a while, but if you make the loop more like 30 seconds long, it should be more brearable without too much more work. I found that some of the blood effects went on to far, and would just eventualy go off-screen. Maybe add in a self-destruct thing in after a few seconds. Overall, a good game. I haven't seen a tower defence game for Ludum Dare in quite a while!

A good start to a game, and though there really isn't any progression, it's fun for the two or three attempts that it takes to survive the initial wave and reach a point of perpetual slaughter. I agree that it would go a long way just to be able to exit with escape. I assume your intention was to have multiple turrets, but understandably had to cut it for scope. Considering that, though, it would be nice to have the single turret selected automatically so you don't have to click it when you start.

good game
