I played through almost all levels :) Cool music, I instantly somehow remembered old game called "Osmos". Gameplay was nice and entertaining, I liked that you introduced new mechanics after few levels (the ability to change frog's "instructions" later). The whole mechanic of programming frog and letting it go sounds for me like those interactive toys for teaching kids how to program :P I liked it, and used the "reset" button and counted frogs so many times (it's great that you display their number, so I can write down and put exactly as many frogs in each state as needed to complete the level correctly, it is extremely useful addition that makes the gameplay much more accessible).
