Dead Cells Review (CrimsonJD)
This is a great game, and I'm nominating it for the Steam "Labor of Love" award, since the devs have been continuously releasing new free updates for a number of years.
It's a really solid action platformer, and rogue-lite game. It can also be very difficult, but over time you do get better. After you beat the game, you can keep playing with higher and higher levels of "boss cells", but the difficulty ramps up exponentially, and since there's not really any new variety, I don't really have the patience to keep playing through all of that. There are a number of levels and extra content, locked behind the 5th boss cell, which only a very small minority of players will ever get to see. Personally I find that a little disappointing, but I guess you can see it as a reward for the truly dedicated.
While it's a great game, I can't really call it a great Metroidvania. The unlocked abilities don't change the gameplay enough for it to qualify, for me. They basically just act as keys for new areas. There is a huge amount of weapon variety to keep things interesting, but I don't think that makes it a Metroidvania. Thus I can't really call it a good Roguevania. Sundered probably takes the crown for that genre. None of this really detracts from Dead Cells, but if you're only playing it because you love Metroidvanias you might be disappointed.
