Very nice graphics and audio, was a little lacking in polish,
for example the hole after the falling shoot thing just disappears, just like the player particles,
i wish there were some more VFX and cool stuff like that.
The UI is probably the cleanest thing i have ever seen, the transitions are top notch!
Gameplay gets a little stale after wave 20 and there isn't much more to do after getting to see every pattern.
Amazing game, very cool!
