Hi,
I understand this is an endless game, I liked it!
The theme is well explained. The sounds are good. The graphics are nice.
The gameplay is well immersive and keeps the attention - good job! I like how the leopards appear in the bushes and how they prepare to jump :).
At some point I became immortal :). That is, extra lives started to accrue for every child I saved, I think I gained more than 5 at a time, maybe because of that.
I like how the gorilla holds the children on top of him. Maybe it would be good to consider their hit-areas also when jumping? :)
As a possible improvement, it would be nice to have a cooperative mode, or even a 2-person multiplayer, similar to the game Fireboy and Watergirl. They can play for one team, 2 gorillas saving children, or whoever saves the most quickly :).
It was fun and really interesting, congratulations!
