Have you considered making a metroidvania game with this spell system? They would be a great fit.
In some sense, the original Bee Magic (and this game) was similar to a metroidvania, though a “true” metroidvania would feature a really big world to explore (I suppose that’s the main thing missing.)
I’m not sure if I’ll make another game in this style. My hope is that other people make games like this; I think there’s a lot of unexplored territory here.
