I like They Bleed Pixels, but I don't have a ton of platforming experience to compare it to. It has an amazing Lovecraftian aesthetic, but/and it's brutally difficult (for me, anyway) and gets a bit repetitive at times. Good concepts, but unfortunately linear.
As an example of this, there's an awesome combo system where you get more points for chaining your attacks, so punching a monster to death gives you less blood or sigil power or whatever than kicking them into the air and chain-punching them off a cliff. When you cap that out, you form a checkpoint wherever you're standing (after a moment of standing still, so you can choose where it goes so long as you keep on the move). That's a neat, organic way to reward interesting combat.
Unfortunately, the game features so many death mazes that the only real spots to put a checkpoint are often pretty preordained, right between the floating spike island jump chain on moving platforms while being hunted by air squid and the wall hopping over spikes while being chased by sawblades corridor. So the game ends up with far less focus on combat and far more on really precise platforming than I'd like, and far less open-endedness and far more rigorous challenge-completing than I'd like.
