This is Harapeko Pakkun/はらぺこパックン for MSX, it is a puzzle game where you play as a little squirrel collecting all the mushrooms on screen and make it to the exit to be rewarded with points. If he skips out on some mushrooms, then you won't be allowed to move on to the next page and will lose 200 seconds on the time. Solve over 30 pages and the game will loop back to the beginning of the first page. As he continues on, red mushrooms will be introduced to make you go around, which adds more difficulty to the game. If the little squirrels time is over, then the game is over. This is a good game to play as I would have to go to the mushroom and choose any path I want, without mushrooms I have nowhere to go. The music while nice and smoothing can get somewhat boring. Movement can get annoying if you play it for so long to the point you will need to stop and think for a moment to let the time run slowly. I've played this game before and at first didn't know what to do, I only managed to beat the first page on my first try. The game doesn't even have any ports released on other systems. Still, I enjoyed it as far as I go on from each.
