Very good game 4.9/5 A few ways to improve this would be too make some extra hard maps, like a few more than usual. then to add to that make a few more modes like an endless mode, or a mode where you have to steal the gems (which i know isnt the point of the game but still would be fun) and finally since there was added achievements, there should be rewards (these were a bunch of other ppls ideas fit into one comment, + so the creator has a better chance of seeing it)
