Ok wow some of those were super hard! If you make a sequel... a suggestion or 2. The biggest thing is a lock piece option. For some of the harder puzzles that would have been immensely helpful. Or at least a way to mark pieces as needed. Also, being able to 'save' progress would be helpful for the more difficult levels. Thanks for the fun game!
I really enjoyed the game, but I also had the server crash and lost the achievement and had to replay the whole game. My only other 2 notes are level numbers would really be helpful along with a menu so you can go back if you can't finish it. And 2, a reset button. On some of the harder levels it would be nice to just start from the beginning instead of trying to figure out where you went wrong.
I really do enjoy the mix of puzzles as well!
I like the concept. If you do make another version you should keep a dont die mode...maybe it just takes points away or something...Also you might want to make the tank and the enemies smaller to allow for more reaction time...all in all, not bad for a 1st game.
I REALLY LOVE THIS GAME!! I hope to see a 'part 2' or more levels some time soon. Though I do have a suggestions...On the levels that can be solved with 3 colors or less, note that at the start of the level or have like a box that says the least possible # of colors...and maybe call it the challenge box or something.
