Hi MightyXray,
I think you did a REALLY good job on your core mechanic- I love the variable difficulty and combining powers. I think it is interesting that players can reveal powers as they play, I can imagine you would start to record frequently used ones on your character sheet.
Side Note: I am hosting a superhero TTRPG game jam and I wanted to extend a personal invitation to join. I am allowing reposts of games, so if nothing else maybe the algorithm will give your game a few more views!

Check out the details on the jam page, and let me know if you have any questions!
