Often these kind of weird looking animations make me chuckle at most, but for some reason this made me really laugh. Arnold's face and the way he walks looks so dumb it's great.

Cute!

Cute! Though I'm not sure about the music choice.

It's a cool concept but a bit too slow. With a game like this where the player has to retry a lot you want them to get back to speed as quickly as possible. But in this game it takes a while to kill a monster. So if I died in level 6 it's gonna take me a while before I get back to level 6, giving me only 5 upgrades. Instead of making the player mana-hungry at the start, I'd suggest finding a way to make that problem appear as you progress. Perhaps the damage you deal is equal to mana-consumption?

It takes way too long for it to get interesting (the sliding being introduced), and even then it's not much of a challenge.

Pretty cool! The tools available are enough to make decent animations.

There's a bug that when you undo sometimes these weird smudges appear all over my drawing. Hopefully that doesn't happen in the full game.

Really cool! I just wanted to let you know I absolutely loved that surprise drop @ 0:23, worked really well!

This song is beautiful. Where is the internet, not listening to your beautiful song?

Really, beautiful.
