Really nice game. I too didn't understand the weapon seeds at first but after reading a comment about it and after some time i figured everything out and it was really fun. Both prices and enemy spawns were pretty well balanced. The pets and upgrades add another layer of complexity but that is good imo. When i died really far into the game i hoped there was some kind of revival system because it felt like i have come so far (maybe that the point is to try keep going but still). Well done.
