This is a weird game. It's a 2D action rogue-light in the style of Binding of Isaac, only it's a sidescroller and feels more depressing than darkly comedic. You are best off going in as blind, so I'm going to go into as little detail as possible regarding the actual gameplay.

This game makes an extremely poor first impression. It leaves players to discover most of its core mechanics on their own, many of which are highly counter intuitive and left deliberately vague. For example, the options menu consists entirely of pictographs. It may take you a few moments to figure out how to simply quit the game without resorting to Alt+F4, assuming you do not delete your save data first.

You will be greatly confused throughout your first few hours with this game due to all the deliberate obfuscation. Many situations will initially seem unreasonably difficult, grindy or outright broken, but after deciphering the games mechanics you will realise that the game is much more forgiving than it may initially seem. Despite having some mechanics also found in idle games, it's not an idle game, nor one that wastes your time. However, it does not hold your hand, as you will need to rely on patience and careful observation to progress at a reasonable pace.

If you do become completely stuck, the major game mechanics are described in steam guides, but I recommend you avoid reading them for as long as your patience lasts. Like a good riddle, much of the fun is in the process of solving it.

I initially found myself taking each level slowly, inching along each level in an effort to avoid damage, but once I knew more of how the games works, I found myself running and gunning quickly through the stages in a way that puts the trailer to shame. The more I play the game, the more I enjoy it. If you have the patience to read through this wall of text, you might enjoy it as well.
