10/10 Fantastic little game, I am very sad that I can't figure out how to play it. The blood runs out very quickly, quicker than I get new blood from the enemies:( I couldn't water the tree because it would lose the precious blood, I couldn't upgrade much:( Maybe there should be an upgrade limiting blood loss? Thank you for joining SKG Community Jam!

EDIT: I went back, re-read the instructions and figured it out, great little game, had so much fun, thank you!
