Hey,
Cool concept, not too far away from mine :D
But i felt it was too punishing when doing the wrong move accidentally, like when you have a plan and then by pushing the wrong button you get a tnt where you cant pull it away anymore, etc. I guess thats just fingermuscle training, but still as its not time related it would be cool to undo the last move to make it less punishing.
Keep it up. And if you ever wanna team up on a future tactic / puzzle game, let me know!
