This is a great a game, I was a bit intimated by the upgrade system at first, but it is surprisingly simple and deep at the same time.
The visual and audio are like ASMR for the eyes and ears.
This game progresses at reasonable rate, always introducing new mod and enemy types to keep the combat fun and engaging.
The level of love and passion that has gone into this game is truly inspiring, words cannot express my admiration for the developers of this game.
