simple idea but very well executed and cute art style! also shooting runes into circle that where off-screen was satisfying!
only gripe I had is that it just felt a bit easy, got till the 7th level but it doesnt looke like they get much harder at all? maybe there could be places that are permanently in the shadow so you have to take a shot instead of going there? I could also see adding more physics interactions like objects that have to be shot away
