I like the art and the blue fires looks and sounds so funny. The mecanic is funny and the paralax effect of the background give live to the game, good job.

Brings me back to the old flash game days; which is awesome!
Having some more camera action when you hit things are have gone a little bit without or are going high up would be great!
An easy way to do this is use Cinemachine since you're using Unity. It's a small thing that would greatly improve the feel of the game.

The upgrades are also nice and I like the menu art style. My only issues with the store menu is that I wish I could voluntarily pop it open with a button before I start a run instead of it popping up right after the end of one. And if the pricing was in the menu, I just clicked and hoped I had enough currency which isn't super fun. But it's a small fix since the rest of the menu is quite nice.

Other than that it does feel like the head doesn't stop fast enough; runs seem to last quite a while. Generally it's nice to keep them short especially early game, longer runs that use skill and upgrades make a great goal for progression.

It's a solid entry that with a little work would be an absolute great example of the era of flash games which stole so much of many gamers minds during school and on library computers.

Good work, I liked the sense of speed, I just missed to leave some blood trail behind hahaha

Very cool! Like the music and the game! Good job!

Really well done! It was satisfying to watch my head barrel through crowds of fleeing graveyard goers. The only minor gripe I had is that it got a little boring after watching my head roll without any available input for so long, I wanted it to slow down. Other than that, I really enjoyed it, it's a creative concept and a 5/5 use of the limitation.
