So there are sevral points worthy of mention here I think.
I liked the particle physics of the gore, and the pixel art is neat too. I really like the look of the goal character's sprite. The flickering torches are great as well! The UI and such does its job, and conveys the pixelated style nicely.
The normal blocks look exactly like the ones my elementary school friend taught me to make, so that's some nostalgia right there!
Mechanics-wise it works just fine.
The level design however, could use some work. Maybe ask yourself "does this type of obstacle add anything to the experience?" or "is this fun, or just tedious to do?". Don't be afraid to rebalance!
It's a cute game, not too long, not too complicated, just a bit tedious and repetitive at times. Good job!
