Nice, simple and adventurous. :) I probably skipped a few of the level layouts (since I assume the numbers by the doors, which you buy through the use of coins, are also level numbers you skip to?) but the ones I did play were all both creative and logic, some of them more challenging than others, all of them easy to understand. The controls were a bit too smooth at times, and it was easy to just slide of platforms by mistake, for example, but it was a fun game! And an inspiring end. Nice work!
