That game was pretty good.
A few small nitpicks though.
Firstly - it felt a bit too much like a player’s success or failure hinged a bit too much on whether or not they could get a turret down during wave 1. On my first attempt - I didn’t manage to get a turret down ASAP, and so I quickly got steamrolled and naturally lost. Second attempt - I made a point of getting a turret down ASAP, and then the rest of the game was a total cakewalk. Secondly - might be worth binding the escape key to a pause screen or something rather than instantly restarting the game when pressed, just to avoid mishaps. Finally - would be nice if it was possible to play the downloadable version in fullscreen rather than being stuck on windowed mode (even after trying to alt+enter to force it into fullscreen).
Still, nice game.
