This one was requested by viewer Andreas M. Weve had some detailed discussions about game difficulty. Based on a Russian video, this game was highly ranked difficulty wise. I can see why. The controls are very delayed and awkward and you need to go through a shitload of stages to get the ending. Took me a while to realise that staying on the perch is a safe spot. I got to stage 3 legit, pretty early on, but after that I start using save states to see up to Stage 11 or 12. This was just to sample the game.
This is a Famicom game, Japan only, but I list these as NES, since they use the same hardware.
