In December 2020 the RVG Squad (with the help of Shallan50k https://www.youtube.com/channel/UCFjZzzJO_rXmr4FeBSf2rcQ) to create a competition for C64 developers to develop a game that could only run in the first 4k of ram, this mean you could not use any memory above the $1000 limit, except for using the C64 I/O chips, Eg. Colour Ram, Sprites etc.
This competition would be running till the end of March 2021 : https://itch.io/jam/the-c64-cassette-50-charity-competition
Now the competition is nearly over, here is part two of a 10 part development series where we develop four games for this competition, which you can see now in the entries of the competition on itch.io 🙂
I hope you enjoy 🙂
