Bloons TD 6, offline games.

Gotta throw vampire survivors in there too even though that's a port of a pc game. That game is just perfect for mobile.

Those are also good too.

However, so much stuff has started on iOS or PC/console, and eventually made it to the other side, that keeping track of exclusivity is difficult if not impossible. I don’t have this list memorized. Most mobile pbone gamers don’t think in terms of exclusivity, they think in terms of good games.

Play the games you enjoy on the computer you want to play them on.

OPUS is legitimately a series I really loved The Day We Found Earth is a gem, it doesn't feel like it was projected as "mobile game, so throwaway waste of time" The story is appealing, graphics is on point stylization, the music is phenomenal

Also, if you want a more arcadey, Bullet Hell Monday Simple to learn, insanely difficult to master, music score is a 10 outta 10
