I played the iOS port, and I know this is going to be a hot take, but it was not that bad. It's certainly playable, but I recommend any other version.

Aside from that, the game's good, with a well rounded lineup of bosses, fun stages, great weapons/upgrades, and great music. I don't even like rock all that much (outside of the Megami Tensei franchise), and this soundtrack was amazing.

Play it in any way you can.
