Understandable, yeah. I went with a pretty unorthodox control scheme in order to keep the mobility style of MH consistent in the translation from 3D and 2D while also not having the mobility restrictions of WASD motion.
Controller support is possible via TurboWarp plugins. It and mobile support (if mobile can even sustain the inefficiency of Scratch games) are options I'd like to have for players in the future.
And yeah, thanks for the positive feedback! There is a solid bit of content in this game I'd say; a lot of the endgame content has been a real struggle for players and would take a lot of practice to beat. In the words of one beta tester, "the second monster is as hard as Fatalis". I keep a running track of my beta testing friends, and only one of them has beaten EX: Maretus or Ultimate Arena.
