Really fun game that I think is on the brink of blowing up.

Gives me DOOM meets Binding of Isaac. Only played an hour so far but I loved it and cant wait to hop back on it. I even included it in my Indie Game Showcase series.

Also, the soundtrack is insane. Props to whoever made it.

Very fun with a great soundtrack and aesthetics but it does have a content problem even with the roguelike randomization.

Finished on first run in under an hour without being close to death once so it is very easy if you are good at shooters.

For the $10 price point, it could use some more features and achievements besides a 1hp mode and melee only. The enemy variety is great though.

Cultic, a very similar game aesthetically, is the same price with much more to offer. I would recommend this for fans of Post Void, Cultic, Mullet Mad Jack, Blood, Hotline Miami or any retro shooters really but waiting for a sale or more content would be better.
