Thanks so much for checking it out!!
The game is currently targeted at PC first and consoles second, which I believe is listed on the Kickstarter page, but its near the bottom and so is easy to miss (something I can fix!).
I'm so glad you're enjoying Mega Man X, its definitely an influence on Super Tobu Adventures! among other influences as well! I still go back to plug in my cart and it from time to time! Chill Penguin is the best ;)
As for the art, all of the character and terrain art has been done by me, as well as the concept and promo art. I did however purchase the trees/rocks, and backgrounds from two artists on itch that do amazing work!
The intention is to redo that art in my own style however, but funding and time will play major roles in how that plays out. I also did all of the Foley and SFX myself, and worked with a close friend to develop the music together. I'd have done that myself also but just didn't have enough time.
Thanks so much for taking an interest! I hope this answers some questions for you :) Have an awesome day!
