Nice arena shooter !
I like how this drops you right into the action, the sprites also look really good, i especially like the SMG, the game is a bit on the hard side though, as the enemies are quite fast and you don’t have a lot of room to move around in this small arena, i even had a glitch where the melee guys got me stuck in a corner and made me clip through the map.
Other than that i still had fun trying this out, and it would be interesting to see what a more fleshed out version would be like with different weapons, a wave system, and maybe even more enemy types to add a bit of variety, you have a solid base there already :)
