my plan for a microvision homebrew.

My plan is to make a Frogger game out of the Cosmic Hunter game. The Cosmic Hunter game has four arrows for the four directional pads, along with a fire button, which in Frogger, isn't really used for anything. Here's what I was thinking:

Since the "Score", "Hunters" and "Skill Level" are etched onto the screen with no way of getting it off, we might as well use them. We'll call "Hunters" lives, with a maximum of two. The Skill Level can have a maximum of 26, but we only need 4. The pixel at the bottom is the "frog", which should be flashing. The lines move from left to right and reappear. The three circles at the right edge of the screen are zeroes for the score. In this screenshot mockup, the player has just started a new game.

Game play rules
the game is simple. Guide the flashing pixel onto the logs without going onto a blank space. Landing on a black space would take a life away and have the player start at the beginning spot as seen on the mockup. The player can only move 9 spaces, so as not to interrupt the skill level and the hunters pixel standings, or the score. Pressing up would move the frog two rows up, so as to land on a log (or water). The five pixels at the top reperesent the five spaces in a traditional Frogger game. Once these are all filled up, the player starts at the beginning, but with faster logs.

level 1 - slow, 5-space logs
level 2 - fast, 5-space logs
level 3 - slow, 3-space logs
level 4 - fast, 3-space logs

After level 4, level 4 just repeats over and over again. The player would just score one point per frog landing. So, the maximum amount of frogs should be 999. I doubt anyone would get past 999, but if they do, I don't know what would happen. Probably make it just roll over to 000 again. So anyway, hopefully this can be made in the allotted space.
