Tangledeep is a roguelike in the vein of ToME, just notably less complex… more mobile-gamey. If you haven’t played that yet then this may be worth checking out so long as you make sure to activate Mana/Stamina regeneration (the respawn rate heavily punishes the default no-regen setting). If you already like that though then there won’t be much for you here.
Another roguelike, Slay the Spire is closer in structure to FTL. The combat is quite different however and resembles a card game, albeit a somewhat 1-sided one since the enemies don’t play cards. The gimmick here is that every replay (a run through the Spire lasts about an hour and a half if you make it to the endboss) requires rebuilding your deck based on what reward options happen to pop-up, with each playable character having different cards to choose from. It’s certainly fun if you can handle the massive amount of deckbulding-related randomness (make sure to prioritize card removal events since you can’t do that manually) and I ended up eventually beating the Spire’s Heart with all three characters:
