OK, I’ll be waiting for the update!
Personally I like the idea of blood arts as it makes everything connected to the blood theme, but standard skills would be nice too as there is only a normal attack. If the skill bonuses could appear more regularly rather than completely randomly it would be nice too.
Maybe you’re thinking of using blood for checkpoints? Would make sense since being able to defeat bosses perfectly means having a lot of blood and it also means you don’t want to fight them again.
Note: I recently discovered that itch app > Downloads popup shows latest updates, so I sometimes use that to check if I missed update emails. Oh, but it doesn’t work when I download the Windows version outside of the itch app, too bad. But I can download the Windows version via the itch app on a PC that has WINE, even if I don’t use it to play (too much CPU consumption), just to see updates. Either way, I regularly check boss fight games so I’ll end up seeing it anyway.
