A pretty decent arena shooter with some small bugs and annoyances. Shopping while the enemy is shooting at you is not the best experience, especially if half of the dropped money lands outside the world bounds. The random weapon shopping is an interesting idea, but coupled with the lack of ammo is not much fun. The uzi feels weak even if the aiming perk is on. The rocket launcher with the infinitely flying rockets is not bad, but it has too few ammo. It seems restarting the game somehow keeps the number of roombas to be generated, so the first wave sometimes can have dozens of them. After an hour of playing and dying again on wave 12 because the shops were overwhelmed by enemies, and even if I had money, it wasn't enough to buy a new weapon just to refill my ammo, I finally gave up. The artwork is adorable, but a little bit bleak. The music and sounds are fitting. Overall it was a fun game, but needs a lot of fixes.
