1000 coins made my game run below 1 FPS. Isometric perspective made everything much more difficult but I was kinda accustomed to it after a while. I managed to get first level with completely white tiles, I think it's something to be proud of. The seal can stand on in-between tiles so it can be hit by two blocks, also moving up-down can sometimes stop when you're close to the edge. I was also pretty bummed out because you can jump to your death on left-right. Multiplying your stash made later levels only about going to the middle and then going back, and buying tar and 1 extra hit a standard practice.
I enjoyed it but I don't think it can be interesting for more than 30 minutes.
