Recommend me some Android games

Not paid but shattered pixel dungeon. Could always donate to the developers though

Bloons TD 6, Chroma Squad, Pocket City 2, Professor Layton, Stardew Valley

Also if you have a Netflix sub, check out their games for Android.

If you tried vampire survivors, you can try magic survival. It's the original bullet hell roguelike, which inspired other genre defining games.

There's 9th dawn rpg 3, which is a good indepth roguelike rpg game. Talking about roguelikes, let's not forget Pocket Rogues. Then there's grimvalor 3rd rpg hack and slash platformer.

You also have Titan Quest (legendary with all DLCs unlocked or regular version with in-app purchases) on mobile.

I also enjoy Undead Horde and Tesla vs lovecraft

Some people mentioned dead cells. Which reminds me that there's a functional port of hollow knight for android. Just search reddit with Google.

Stardew Valley

I know, I know, but Flappy Bird.
It won't be long before you won't be able to play it anymore. This is due to Flappy Bird being 32-bit, and support for 32-bit apps is ending.

For example, the Google Pixel 7 already blocks installation of 32-bit apps.
Also, the new SoC designs won't inlude 32-bit support, which will be the hardware-dictated end of such apps.
Enjoy it while possible.

Anyway, my favorites are Bus Simulator: Ultimate and Truckers of Europe 3.
Though, you may find them boring.
If you do try them though, be ready for your phone to turn into portable cooker. The heat already killed one motherboard in my phone. The other one had different issue.
Yes, my phone already had 2 in-warranty motherboard replacements. Poco X3 Pro, what do I say. A pretty common issue.
Generally your phone will just slow down instead of cooking itself, but that doesn't mean the heat should be ignored.
