Th visual are nice, the bosses looks really cool, such as the walk animation of the second boss and the phase transition of the second and third boss. The music are nice too.
The gameplay are cool, the exchange hp for ammo with the extra blood that keep respawning and the blood that drop by enemies really helps makes a balanced and challenging fight. Tho the jump pad is a bit slow, which make it a bit annoying to use but its fine.
Overall, really cool game!
