what is the theme of the jam??
There isn't really a theme, you can basically do whatever you want.
You are encouraged to include a gesture to Rainbow Islands, this could be used to influence your design or it could be a simple inclusion in the game.
Your main constraint is that the game must run on the Amstrad CPC 464 rather than a thematic one.
Hello GracHeer and welcome to the CPCRetroDev.
As awergh told you (thank you, awergh), the CPCRetroDev is not a jam as it.
This contest consists of developing a video game for an Amstrad CPC 464, a computer from the eighties!
That's why there is no theme as such, I guess it's already enough with this to add more difficulty hahaha
However, every year we like to dedicate the contest to a well-known game that turns 30 years old on this computer, as is the case of Rainbow Islands. So it is rewarded if you make a small Easter Egg to the game or any representative element.
If you want to participate you are still on time, we will be happy to receive you! And if you don't know how to develop for this machine, I recommend you to check out cpctelera, a very useful little framework for Amstrad development. It even allows you to port your game to Android platforms!
If all this catches your attention, but you think you're not in time, we'll be back next year with the tenth edition! Come on, join us!
