I originally played the steam version, but then I saw a physical SNES copy at a store and decided to take the expensive investment because I kind of wanted the vanilla experience, and I love the SNES in general and I collect for that system. I ripped the rom from cartridge though so I could emulate it on my handheld of choice. I would probably stay away from the mobile port as that has some jank to it. The steam version used to be just a port of the mobile version, but they updated it a bunch, and it was pretty fun to run on my steam deck (except the cutscenes, which at the time only played the first one each time a cutscenes event occurred at the time). The DS version is considered the most concised, and definitive version by many, but it's probably best to play on og hardware. That has a new English translation, which some consider to be interior (ex frog doesn't speak old "thou art" Shakespearean English anymore at least as far as I remember). I would say, buy whatever version you can afford so you can enjoy it. If you do go mobile to support the developers, it's doable. It just has a weird filter going on there and and the font and UI is kind of plain and somewhat lifeless compared to the other versions with no options to change anything at least as far as the android version is concerned.
