This is SUCH a cool game, so much cooler than I could do!
The slice is just so fun to play around with and the juice is fun to play with. The enemies are really cool, and their art is awesome! The underwater wave effect is really cool, and its cooled down enough to see the gameplay. The combo system is AWESOME, and its fun to mess around with trying to get combos. You went above and beyond, and set my bar really high.
There are only a few problems. Losing HP while moving is a bit annoying, and showing the hiboxes with z, isn't too useful, I would replace it with a 2 HP charge up dash n' slice or an aimbot that uses 3 HP to start up. Another thing is that you don't get to retain your combo score from the last wave, since the combo end timer is too short, and the wave start timer is too long.
I absolutely LOVE this game, and I can feel like I'm in an arcade from the 90's (I was born 2000s, but whatever). Good luck!
