I like how simple your look is. It is fitting to the gameplay and the world you created.
It would have been nice to have a beginner area first where you can't die and get a small tutorial as well.
The sounds were good and I liked the music, but the sound you play, whenever the text appears is a bit annoying since it repeats itself a lot and is quite high pitch.
Keep up the good work :)
PS: I would love to get a rating as well ;)
