Made a quick and buggy (hah) Frogger.

I wanted to try an hypothesis: I don't think that in the Atari version they do any collision detection at all. Instead, they may use a formula to check whether current position is occupied by an item or not.

Formula in function positem() returns an x position depending on a direction, speed and offset, and is used to draw items and also for checking if there is something on frogger's position (checkrow())

Hi! new here. This is my third demo in PICO, a classic demoscene effect. I tried giving some shading using tline(), but failed.. I need more practice! :P
