I couldn't find this very very sweet and joyful platform game.
It's a Russian platform game sold out to States and several countries of earth with English version.
Gorbi is the English version, which has set-up in 1991, referencing Gorbacov.
A cute little lake frog tries to survive in the spring, jumping between leaves on the surface of the lake. But each time he jumps onto a new leaf, he doesn't have much time, otherwise he sinks with the leaf to the bottom of the lake and dies, <GAME OVER>. It's getting harder and harder, needs to be careful with fast reflexes to catch nearest leaf to jump on it.

I couldn't find Gorbi in your database. If it's here please reply and let me know. If it's not here. Please add this awesome platform game!
