Played for 40 minutes and after learning to merge stuff and breaking everything on the map I can´t say I understand the goal of the game.
However, I kept playing because it was satisfying to break things with the rocks, maybe could be better if merges guys didn't break after 1 hit or having to keep picking them up after every hit but it was still a fun toy. It seems like it could be a fun sandbox type game where you expand your area and watch the lil guys just hang out. Art style was very nice and the lil guys are very cute :)
But yeah, if there is an end goal I feel it needs to be better conveyed. I imagine it has something to do with the furnace but I put a lot of things near it and nothing ever happened.
