Paint the Town Red is a chaotic first person melee combat game set in different locations and time periods. The voxel-based enemies can be punched, bashed, kicked, stabbed and sliced completely dynamically using almost anything that isn't nailed down.
This is a very difficult game for me. There were a lot of attempts to reach and kill the last boss, but I managed and finished the game. Also, at the end of the game, I received an achievement that only 1.9% of players have, that is, few people made it to the end
