Grindstone — is a battered puzzle game about a very angry guy who chops small cartoon critters into pieces and gets jewelry for it. The goal in Grindstone is to connect as many creatures as possible in one line, after which a very angry man starts to shred them. Additional conditions are constantly changing: obstacles appear somewhere, you cannot stop on some cells so as not to fall under the distribution, sometimes you have to catch a special creature in order to get the key to the chest, and sometimes bosses with new mechanics are encountered. Between races, you can take a break in the tavern and, say, change your equipment.
