I'm new to game jam. I just read the rules there is nothing that would interfere with a small update.
- All sprites and images must be 8x8, unless said otherwise in "Exceptions".
- All games must be family-friendly, no NSFW content.
- All entries must include the source code of your game. This is to give people a chance to build off your game and to prove you did, in fact, actually use 8x8 sprites.
- All ratings must be fair, so please be kind when voting.
But thank you I'll keep this in mind in the future!
