The wave 6 infinitely loops, right?
The game is pretty good, I like the visuals and the animations especially, the bullet speed and the movement speed feel right and then the gunplay feels good, the enemy variation is not exceptional but at very least the ones with the visible targetting are a pretty good variant. The speed of the different enemies appearing seems right too and the game also offers the right level of challenge, it's satisfying to deal with it.
Very cool and fun game, thanks for sharing.
