This is definitely the most fun game Ive played so far! The tutorial was super serious, the gameplay was fun and enjoyable and the upgrades were really well though out. I only had a few nitpicks, like how you can lose yourself on the screen very easily, how enemies can be hidden behind the UI at times and how you cant see what items do in the shop.
This was also another minor issue, but at the beginning before I purged all my blood bullets I was looking back and forth between my player and my bullets to avoid the blood ones, taking me away from the combat, maybe this can be solved by move the UI above the player and making it smaller, idk, its not a big issues if the player decides to purge their blood bullets.
Still overall it was the most fun game I played during the jam and the tutorial was really funny, god bless you tutorial Larry.
