I get the no gore part. To me that means guts and body parts. What about blood splatter via particle effects? How much is too much? My idea involves a lot of splatter. I can message you on discord if you need more details
If it involves a lot of splatter, then it is too much. I wouldn't mind it if it's subtle or in low quantity, but if you judge it's a lot of splatter, it probably is too much.
Yep, you could do a goreless version for the jam and add the splatter after it ends. I would also accept it if you had an on/off option to toggle the splatter.
The problem with the game idea in question is that blood is in the name. And it just wouldn't be that game without gratuitous amounts of blood. I have another idea i can bring to the table though.
