Finished Deedlit in Wonder Labyrinth.
I liked it, while it is basically "just" a Castlevania clone it has one particular mechanic that made it interesting in its own way.
You get Wind and Fire magic early on. You can switch between them, one is always active. You level up magic by landing hits (up to 3 levels), but it levels down whenever you get hit. When you reach level 3 with an active magic, you regen HP constantly. So if you're like me you'll always attack while the lowest level magic is active, then switch over to level 3 during brief respites to get your health back, then switch back whenever you're about to jump back in or get hit.
This becomes complicated with the introduction of enemies that only take damage when a specific magic is active, and AoE attacks you can nullify with the correct active magic, and barriers you can cross depending on what you have active, etc. But never to the point of where it becomes frustrating. It simply becomes a game of switching gears and trading off advantages.
The other thing I would note, as short as the game can be, is that it's excellently paced and keeps throwing new things your way to keep you engaged. Different kinds of hurdles, abilities, enemies, bosses, whatever. You're always a few rooms from something new. The pacing never really wavers. Although I did find the story beats got old and repetitive pretty fast.
The ending accounts for the fever dream narrative but I'm not convinced it was worth it.
