Definitely needs work...
Add some power-ups, speed it up a little, and make it so that the paddle actually works. I "missed" several times when the paddle should have hit. 1/5 until those things are fixed/added.
I've really enjoyed this game... With the badges added now, it definitely gets 5/5.
My only problem I've found is the "Smite I" skill always reverts to 0/25 when the game is loaded. I've mastered it probably 20 times over now.
Could've been a lot better... I agree with everyone else, the game is way too repetitive. Maybe add some upgrades, a health bar would be nice, plus some sort of objective display.
Still got 4/5 though for me.
