oh and an "donate all blood" button would be nice.
since, even holding down the mosue, it jsut takes a bit too long for my taste to spent those 1000 blood :-)
currency system a little funky but blood crystals do come from donating blood. And 100% I want a higher prestige system I was gonna make a prestige shop where you can unlock more weapons / tower modifications (like making the tower melee and tanky), but this is the basis I had. It was for a game jam and the main part of this game was made in ~5 or so days so I apologize, but hoping good things in the future for it!
