In the latest update, Holocure (in its quest to be every game ever) added, among a lot of other things, a rage platformer called 'Tower of Suffering'. It's basically a miniature version of Jump King with a couple of quality-of-life features to make it beatable for non-rage-game players, including a power meter so you can gauge your jumps more easily and the ability (albeit extremely limited) to place checkpoints you can return to as many times as you need to. It's still ultimately a rage platformer, though, so long falls, impossible-looking jumps and general 'why' moments are inevitable.
At least it was short enough that a guy like me who's never actually played Jump King could beat it and see the cute girl at the top.
As for the actual 0.7 update, basically it just made the game even bigger and better like all the other updates so far. New units, new mechanics, new minigames, a couple of new stages to kick your ass until you get those new mechanics unlocked and mastered. Game's good, and if you liked Vampire Survivors I'd suggest taking a look even if you know nothing about VTubers.
