Overpaint is a puzzle game where your objective is to use three panels to cover their matching colorful circles from the board. The app gives you access to dozens of challenging levels, automatically saves your progress within your Game Center account, and provides you with detailed gameplay instructions.
When playing the first couple of missions you have access to some indications regarding how to complete the levels. For instance, on your first challenge the app teaches you how to cover the circles with just one move by dragging the panel over the matching geometrical shape.
You have 5 chances to complete a level. Once you lose a chance, it will refill in 30 minutes. Also, on each mission you have a certain amount of moves available. Make sure you use them wisely or will need to replay the mission and lose a life.
The one thing that bothers me about this puzzle game is the fact that it crashes every time I complete a challenge. According to a comment left on the download page, another user also encountered this issue. Hopefully it will be fixed because the game is quite fun to play.
Personally, I would keep this app installed on my Mac and continue playing the game if it wouldn't come with the aforementioned problem. Hence, I'd suggest that you try this game once the issue is fixed.
