Man whoever did the music did a nice job. I think with some sound effects and a few quality of life improvements this would be really good.
I played for a while until a big slug guy showed up. After that I wasn't sure if there was an ending or if the game just goes on forever.
Some upgrades would be nice to make your weapons better each round.
The melee weapon felt incomplete, there is no visual indication of swinging, and it was unclear where to click to hit enemies. I preferred using the ranged and bomb attacks.
