Roy has done some great C64 games in recent times, and Jumpy64 was one of a few in the pipeline that had some particular promise.
Jumpy64 was framed within a Game Boy style screen and made to feel like an early Game Boy title in colour. The game itself was a single screen platformer where you had to collect items and likely reach an exit – essentially a sort of Manic Miner clone.
Sadly it seems that Roy has decided to abandon this concept, and at this stage it is mostly just a concept. You can move your main character around the screen, but you can easily get out of the map and there isn’t much to do at this very early stage. It is a very early glimpse of what could have been an interesting title.
