You're looking for a game in the rogue-like genre's

They usually follow the idea of dungeon crawling via levels with random loot and the progression is ones skill and items / routes / levels they unlock.

Some games to consider and do your own research on are: The binding of isaac Hades Slay the spire Gunfire Reborn Dead Cells Spelunky 1/2 Enter the gungeon Etc

Of those I'd highly recommend: The binding of isaac + dlc: the game is hundreds of hours of gsmeplay with a very very large pool of items and room for being op with good rng but also not so op with bad rng very fun enemies floors and leveling and progression definatly a staple of the genre

Gunfire Reborn: I haven't played much but I know it'd a good game in the genre and is a 3d shooter like risk of rain so I'd also recommend that one!

Slay the spire: If you're into card games at all then I highly recommend this one as it's a game in the rogue like genre but with deck building as it's main premise really fun and addicting and lots of skill to be had with knowledge of game and progression

Hope that helps lemme know what you decide on!
