I used to have this phone game gasp I know called Archero installed on my phone.. two? phones ago.
Its basically a roguelite of sorts where you beat stages that get harder and harder, get gear etc.
I recently reinstalled it as the only game except Wordle on my phone and I have to admit it takes up a good bit of time when im waiting for a train/bus or other "nothing else to do" scenarios
I haven't spent any money but they're generous enough to where I don't have to.
Gotta say though, I am a fiend for a bit of Hearthstone: Battlegrounds if i'm talking to a friend and waiting to do something else or watching a video on the weekends 😆
