Wow what a lovely comment! Thank you so much for the kind words and I'm glad you enjoyed it! The difficulty curve definitly needs work and I want to tweak the ability swap controls for sure. I plan on expanding this game and the first thing I think i'll do is get controller support. I feel like it will help.
Game Maker Studio is such a powerful tool now and if you know how to work it, you can make some really cool stuff with it. There are a few great tutorials online but I would love to chat about it if you ever wanted to. Hit me up on discord or something. #0449
Also, I'm going to go check out your game too!
