I was able to finish the whole game and really enjoyed it! The other comments had me worried, but it all really was possible! (though I think I might have 'cheated' for B+, i just jumped over the teleporter completely haha. And yeah it seemed like there was a limit of 3 clones? I don't know if that was intended or not?
But apart form that, this was a great game! I loved that you let the player just infinitely get smaller!!! I swear I got Antman-quantum-level small at one point ahahaha. And the clones were really fun! I enjoyed some of the later level design too! Very tricky!
The music, art and animation was great too! Good job!!!
