You're a velociraptor and strangely enough you're fond of fruit! Apparently in prehistoric times as well, there were strange exceptions. You're hunting cherries, apples, grapes, melons and bananad, but you're scared to death to get chili peppers in your mouth! Keep walking inside the screen and don't fall into the hot lava.
Use the left and right arrow keys to walk. Press the up arrow to jump. If you press the up arrow twice, you jump twice as high. That's useful for catching fruits that float a bit higher, or for reaching platforms that you can't reach in one single jump!
