This is just a little update on some of the mobile games I've been playing. From worst to best
Opsu:
An open source osu client. You can download beatmaps from various clients, and play osu on the go. It's... Okay. Osu isn't really a game to take on the go tbh, and for me, the offset was garbage. Getting it correct was a pain. It's still just osu, even though I don't like the skin much either.
Tuber simulator:
Decent game that I wake up with. It's kinda rewarding with the constant improvement. Although it crashes on 8.0 a lot.
Fire Emblem Heroes:
A great mobile fire emblem game. Had gacha elements, but is super easy to play, and you don't need amazing heroes to win if you're smart enough.
