I think it's normal not knowing what to advice, it's pretty far away from the standard idea of a "game".
For the graphics I tried going for a "drawn on the copybook" kinda vibe, I would have loved to draw and scan all of the assets, but I didn't have the time :( I managed to put in a photo of my copybook as the background, to sell the idea.
I don't think it's a Steam kind of game, and it isn't meant to be, BUT if I had to find it a spot in the world, it might be a free resource for middle school teachers to teach basic equations with X and Y to students in a "gamey" and interactive kind of way.
I definetly have to improve my musical skills, I promise I'll try blending it nicer next time!
Tell me the one you think you solved, and what were your results, because I might have rushed and not have found all the possibilities! It happened in the past with another level I ended up scrapping, nothing new!
I'm really glad you were positively impressed, I'm shaking! And (as I once read on a YT comment somewhere) thanks for the internet-triggered dopamine! <3
(P.S.: Also I'm from Italy, so maybe we write the "power" in a different manner, I didn't want to just make it a smaller X or an * though)
