I think a double jump system would have been more effective than how long you hold down the button. 1 pecosecond of the jump button can take you from a micrometer to a kilometer difference in your jump. Also, I don't exaggerate.
This game has promise, but it in all honestly isn't good enough to get hours of play time grinding for hard badges. I think you have a good concept here but you need to listen to the feedback of your players and make some tweaks. Without some improvement I don't see myself ever playing this series again.
It's frustrating. I love minesweeper and am quite good at it, and have been hoping for a new take on it for a long time. I don't think this is the right take. At least a mode to ONLY play minesweeper would be a nice break from the random chaos that is every level.
