This game is really good, it has great elements of an infinite runner and a platformer which is cool to see. The music in the game fits the whole pixel style as it gives me a nostalgic feeling of the classic music heard in early pixel games. The level design is great too, although sometimes when I started the game I was stuck between platforms, this could be an issue with the players collider or bad luck RNG. Other things I liked about the game was the animation, however, i feel like an idle animation would have been cool as in some moments I was standing still and the running animation carried on playing which looked a little odd. I liked the use of the question and exclamation marks above the player to indicate where the falling fire balls will land, I also like the use of the timer and the collectables as they give the player in incentive to keep moving and playing the game as they would want to beat their high score.
There are a few changes I would make to the game, these include, changing the background as it is blurry, most of the writing in the game doesn't follow the same font pattern so using a pixel font would make it all work together and I feel that the colliders on the player and the platforms are too big so changing them to make easier movement would be fantastic.
Great game!
