The visual are nice, the phase transition of the bosses look really cool, especially the gula boss. The boss fights are cool too, its quite challenging and fun. The gameplay are interesting, the blood exchange to attack with the adrenaline power is nice, its have very high damage but can drain most of your hp very quick, basically high rsik high reward.
Tho not sure if its a bug or not but sometime the player is not able to move to certain direction. Also, kinda wish that the satan is fightable, its looks pretty cool.
Anyways, nice game!
