I assume this game was rather designed for touchscreens. I played it on mouse and well... I don't think it was as engaging as playing on the touch screen would be. Apart from that, we get yet another pixelated excuse for graphics and decent, little gameplay. I played little, reached 18th level and I think that I've experienced all the game has to offer. The "restart 5 levels below dying level" mechanic was a positive suprise to me, and that's cool. The treasure and high score surely motivate player to risk and play more.
As far as I'm concerned, enemies move quite randomly, maybe with prefference to reach player when he's nearby, so they're pretty easy to avoid. Multiplying them was a good choice. However, on the levels with 3x3 grid it is actually possible to get to the exit before enemies make second move, so if after the first move exit isn't blocked, you pretty much won the level. Knowing this, I was glad to see, that the grid got bigger later on.
It's not a game that I would come back to after some time, unfortunately.
