Fluff game. By that I mean there's no substance to it. It's not a very intriguing puzzle to solve. Why? It's nearly impossible to find a solution by calculation or planning, but it's easy to stumble into one by dumb luck. It is not a puzzle that lends itself toward comprehension by the human mind. Not the worst I have seen mind you - that honor belongs to nuclearoids. But fluff nonetheless. Also you need to give frigging instructions. The author comments are unsatisfactory. Also there's a bug. It gave me the "silver medal" for getting 3 stars on the first 30 levels. Only I didn't. 21 and 26 are 2 stars out of 3.
