I really liked the spritework but didn't much enjoy how everything being the same color as the bullets made it really hard to see, especially with the blood particles (which thankfully were possible to turn off)
I also don't think screenshake on every bullet fired was necessarily the right play, it'd have been fine if it were on just enemy kills or something.
The pick 3 implementation was solid and things generally worked as they were supposed to. Sorry to hear you got sick before implementing the final boss but the text made me laugh so it didn't make me dock points
