The movement was hard to control at first, but I had fun getting it down. Well done!

Its simple but fun.

Not bad at all, but isn't very polished

It's a bit tricky to play, but it's not bad it's just that the character and the fire effects don't quite match up. It might be a free asset. The surrounding structures are just plain blocks, and the menu doesn't look very polished, but other than that, it's pretty okay.

First, good job for participating in this jam ! Second, your game here, has a decent mastery curve and it's fun but playing it in a small browser frame makes it too hard. Fortunately, I noticed the Unity fullscreen button and then I really enjoyed it. Maybe you should consider adding this advice to your game description so it has more chance to really shine.
