Dead Cells - Currently $16 on Steam Early Accesshttp://store.steampowered.com/app/588650/Dead_Cells/
Dead Cells is a 2D action-platformer / rogue-lite, currently in early access. Much in the same vein as Rogue Legacy the game is run based with persistent upgrades that make your future runs easier allowing you to make it deeper into the castle. The map, weapons and even doors are reminiscent of some of the 2D Castlevania games. The game has a pixel art style with some bloom effects that really make it look great.
One of my favorite parts of the game is the combat and the feel of the game. There are a variety of movement skills such as double jump, ground smash, ledge grabs and a dodge roll. There's also a variety of weapons and styles to play around with. You can use a short ranged daggers with high combo damage or a long range whip with lower damage along with various traps, spells, bows and shields. The enemies will charge at you forcing you to block or will employ various kinds of shields requiring you to dodge behind them or stun them.
The game also incorporates some Souls games elements. Killing enemies causes them to occasionally drop 'cells' (souls) that you collect through your run and are used as the permanent upgrade currency. However to spend them you have to survive to the next area. Occasionally you will run across other other powers that will enable different routes or shortcuts through the castle. There's also a gem like currency used for opening treasure doors and spending at Spelunky-like shops.
One knock against the game is that currently reuses many of the same enemies as you progress through the areas. It does introduce some new ones as well, but the old ones seem to stick around. Also although there is a Rogue Legacy style upgrade tree, it doesn't look nearly as big or have as much variety. Hopefully their goal for getting out of early access is to just increase the variety across the board. More enemies, more weapons, more upgrades.
These are just my initial impressions but I like the game quite a bit so far. That said, I'm only about 2-3 hours in. Whether or not there's enough game for the full price at the moment, I'm not sure yet.
