Flame Keeper

The coolest thing about Flame Keeper is all the different buffs you can purchase as you proceed through the game. It's fundamentally pretty simple and repetitive, but the constant "rolling" for new perks, buying upgrades and picking up various little benefits to alter the play style makes the game fun and addictive. You mostly just pick up runes and put them in a fire pit in the first two stages. To do this you need to sacrifice health. You can get health back by defeating enemies, breaking things in the environment and picking up regeneration benefits. On the third stage you have to defend the fire pit. This involves putting life energy into traps and killing enemies as they come. While it's kind of a "tower defense" game here it's so simple and shallow you don't really need to do much once you know how it works. At the end of each of the four worlds there is a boss fight and these are pretty well done. If you die at any point up to the boss or base defense game you have to start the whole level over. This sort of makes it a rogeulite, since you need to pick up specific abilities on the run to ensure survivability, but this game is super easy once you know how to play it. The only really frustrating thing is the "stamina" bar. Jumping eats stamina so if you jump too many times you will be locked in place. On some stages you might get trapped on a platform and die this way. Beyond that, the combat is fun and there's tons of stuff to buy as you unlock parts of the home base. You can upgrade your abilities, buy little "pin" perks, buy new weapons, etc. It's not incredibly complex but there's a ton of variety, and while this won't go down as a classic I had a lot of fun playing through it on both normal and hard difficulty. The achievements are really easy and you don't even need to finish the game to unlock them.
