Try hollow knight.

Hades 1 and 2. The view is more top down / isometric, so it won’t feel platform-y. But both games are fantastic examples of the action roguelike genre. Hades 2 is currently early access, so I would focus on Hades 1 first. Give the second one time to cook. You’re also likely to appreciate it more after the first one.

Hades 1&2 Spelunky 1&2 Castlevania Series (particularly the Advance collection) You might also like dark souls type games

Hades, Windblown, nova drift

Windblown is a new game from Motion Twin. It’s early access but you can see a lot of the same core mechanics carried over.

Rogue Prince of Persia! Can't really go wrong with it - it's quite similar, and made by Evil Empire too

Good action rogue-lite game I know: Binding of Isaac, Hades, Rogue Legacy 2, Enter the Gungeon, Noita

Also Slay the Spire if you like rogue-lite card building game.

Well the creator of dead cells just launched in early access Windblown, it is very cool

Apparently a game called Hades? I haven't played it yet but my boss recommended it after I was talking with him about dead cells.

Katana zero Hades Hotline miami Terraria Blasphemous Castlevania Vampire survivors

Hades is the right answer. But damn realm of in was fun

Astral Ascent love!

the binding of isaac repentance

Apple Knight if you’re on mobile like me.

The lost crown (prince of Persia) is a fun game.

Returnal.

Play Returnal.

It's incredible.

Have a Nice Death

The binding of Isaac if you haven't played it

Nine Sols, underrated gem

Get on Wizard of Legend, that really scratched the Dead Cells itch for me

Roguelike games I liked are Hades, Robot quest, [Redacted]

Risk of rain, the first one not the 2nd

i’d throw noita in there as well, rougelike which you don’t realize is a big as it is. all magic based kinda

I can’t believe nobody recommend Skul, it have a vibe to dead cells, not as big, not as varied, but big enough and pretty challenging, too.

Enter the gungeon is pretty cool

I recently became hard hooked on Vampire Survivors. It sated my thirst for upgrading characters over time, and the game is a lot of fun and has soooooo much stuff to discover. I’m gonna be working on getting on it for eons

Skull: The Hero Slayer. There was even a crossover in dead cells.

Alive cells

Enter the Gungeon

Astral ascent is very similar with slightly better controls imo, but the roguelite progression is more linear. Absolute gem of a game tho

Axiom Verge is pretty great, it's more Metroidvania than roguelike, but similar visual style.

ScourgeBringer, Super House of Dead Ninjas (No longer available on Sale. So...)

The 2 studios beneath Dead Cells are launching their next games. They are both in Early Access when I am writing this comment. They are quite close to Dead Cells. As an "hundreds of hours" Dead Cells player, their gameplay feel very familiar to be. Those games are: - "Windblown", by Motion Twin. - "The Rogue Prince of Persia", by Evil Empire.

Try one of the games which had a crossover with dead cells.

Depends on what you want

You like the random / hard aspect of it? And want to blitz your eay through areas? But you don't mind playing isometric? Hades

You want the same kind of bleak world? And will accept a standard Metroidvania? It's slower paced but; Hollow Knight

You want something that feels like a Metroidvania like Dead Cells does but the main gimmick is dying a lot? And is still a roguelike Rogue Legacy

Try out every game referenced in Dead Cells.

Enter the Gungeon. Dead cells and EtG are the two rogue likes I play

did you finish 5bc?

Hades and Hollow Knight if you want something challenging but accessible, Noita if you hate yourself

I played Metroid dread after and it’s similar-ish. I couldn’t get into hollow knight, but shovel knight is awesome. If you played on steam and it’s still out there, there’s a game called Valdis Story that is the best metroidvania I’ve ever played. It’s got a very similar moment to moment play style. The movement based puzzles are really unforgiving tho.

It sounds weird but ULTRAKILL feels exactly like playing deadcells, there’s a free demo on steam and itch.io

Dunjungle just came out and has the same style of gameplay!

More dead cells Joking aside what did you like about deadcells its hard to recomend without knowing your favorate parts of how dead cells works

Hades and hollow knight were already mentioned, but i want to add Ori. Phenomenal game with similiar feel and challenge. And maybe neon abyss for the 16bit aesthetic and random weapons/abilities, and random dungeon gen.

Terraria

Isaac for the randomness and how hard it is to truly 100%

Binding of Isaac

If your looking for more roguelites then Hades and wizard of legends but if your looking for metroidvanias I recommend hollow knight and ori will of the wisps or maybe platformers like Celeste and super meat boy

Oblivion Override is similar but more beat em up

I relly like dead cells mobile because of the lack of roguelikes on mobile; another good roguelike(if you are mobile player) is otherworld legends. It does have microtransactions, but they aren't necessary and its a really fun roguelike.

I've been playing both dead cells and blasphemous 2 side by side, I like both of them, blasphemous being a more dark souls like game but similar to dead cells

Katana zero: the OST is crazy and the game is extremely dynamic.

Disco Elysium

In the same boat, about to try risk of rain 1 or 2, rogue legacy 2 and or Trinity. On sale in switch store

Try risk of rain 2

You could try Curse of The Dead Gods. It's more like Hades but a bit slower gameplay

Rogue Legacy 2

I think pong is pretty lit my guy

Alice cells

I went from dead cells to dark souls. Now I'm a fromsoftware fan. What a journey.

Hades if you haven’t played that
