I want to stay away from letting brown do too much, since I feel like it already gets a lot of love, but I do like the cum production/lactation play idea for blue. I think I'll throw that into some scenarios as an extra minor light interaction since it's not really something strong/exciting enough on its own.Fuck... It would be awesome if blue let you do liquid metal terminator shenanigans. Like render your body into a fluid and flow past locked doors via any cracks / openings that aren't air tight. Hmm if you want you could also split transformation between blue and brown. Brown could be augmenting others while blue could be augmenting / transforming ones self. IE with blue your own form becomes malleable and fluid.
Alternatively you could do things like crank up fluid production to do things like cum and lactation play. IE have the MC start cumming hard enough to be a one man bukkake party/ gokkun faucet. Or somehow reach out into girls body with blue magic to induce lactation. (Depending on how niche you're willing to go kink wise I suppose water sports is also potentially an option.)
Yeah, I'm hoping to offer solutions in such a way that no problem doesn't get solved just because I didn't give you the 'right' tool even though you should've had it. But it's definitely something I'm keeping in mind.The problem ofc with giving so many ways a magic school can be used is the "Why didn't MC use this spell to solve this problem?" dilemma, aka the Harry Potter Amnesia problem. It's sorta avoided here because it's explicitly mentioned that the MC has little to no control or understanding of the magic he's using, so the results are unpredictable and he can't always get the effects he wants, but it will definitely become an issue as the effects become more powerful.
(Also mod options please... this game and setting just feels ripe for adding custom scenarios, characters, and all kinds of shenanigans and fetishes).
Someone on Patreon asked about mod options as well, but I'll tell you what I told them: I don't know what I'm supposed to do on my end to accommodate that lol. I'm making the game in Twine if that helps. I didn't think modders needed me to do anything extra to support it, but if someone has a specific outline of things for me to do I'm not opposed to it.
