of course sound is missing , and according to me, a little shackscreen effect too, but good work anyway. Have a nice jam :)

Interesting ! Too bad there are no sounds or music.
Two crystal had left, one on top and one at bottom, and monsters doesn't attacked them because they only came to me, i i was just staying at the middle of the map and hit them . Maybe something to improve here in order to ameliorate gameplay ?
Otherwise, good work !

I found the gameplay a bit frustrating but I do really like your cover art! :)

Neat attacking concept. It's quite fun once you get the hang of it.

The art at the start screen looks really nice.
