Too much of Silksong's difficulty is just numbers. Shitty peon enemies hit for two health because fuck you. Touching a boss while it's stunned hits for two health because fuck you.

And then there's the whole shard system, which straight-up doesn't need to exist since it just makes you never engage with tools. Until you use them to nuke a boss in its final phase, of course, because the alternative is playing RNG roulette against the boss's 3 adds (that each hit for two damage, naturally).

It's a great game, but it definitely isn't a perfect game.

They need to remove shards, tweak (lower) the power of tools, and adjust outgoing damage (ideally through armor-like upgrades you earn).
Oh, and crests were not the right call. We all just use the Reaper (unless we're further exploiting tools with that other crest).
