The initial system actually had you painting the ground itself, which would add color to the world and allow you to place effects at precise locations for use in the future and allow you to place effects next to each other for a kind of “combined” effect (i.e. speed paint next to bounce paint allows you to keep momentum and launch further). Though I’ve never played it myself, the original intention was for an almost “Animal Well”-like system of discrete “tools” (the paints) that you could use and combine in various situations to come up with your own solutions.
The “mixing paints” idea you had was also a consideration after I realized that the above would not be feasible with the time on hand. I had intended it to straight up combine the effects, as they were designed in such a way that most would combine without issue. But then I realized I wouldn’t even have time for all the base powers, much less the combined ones lol.
Now, this discussion has got me wondering if there’s a way to combine the two systems. Hmmm…definitely lots to think about. Thanks for this! Never would have considered it without your ideas/brainstorming :)
