Hello!
Your game Mavea is very close to the kind of game I would like to make. In fact my ludum dare compo The last ritual is very similar (weird first person puzzle with "moebius" art style).
I kinda overused this art style, though (already 4 jams) so if I'm the one doing the graphics I will experiment with something else (but in the same minimalist idea).
I will make a discord server so we can discuss.
