Hmm, I see. When I had my friends play test it they got it so it seemed the instructions in game were enough (maybe we just think alike lol), but I'll add a more thorough explanation on how to play on the game page. Thanks for playing!
I watched it and I was in pain watching LOL you were so close to getting it but yeah I think I see why people can get confused, I should have explained in game that the first domino you place is the one that gets pushed and starts the chain reaction to hit the enemy at the end with the combined damage. Also even after you beat the smolem you got the quest bug, so double pain. Anyway, definitely the camera was not good, it was the first thing I coded and the gameplay quickly evolved past it and never had time to go back to fix it. Thanks for the feedback!
