I don't know why but game did not worked the first time enemies didn't spawn but now it's works. There is a lot to do you can add sword animations and sounds. I think theme is good but game feels unfinished but if you build on it it can be good.

Cool idea for a them, I really enjoyed using the dash ability! the need to reposition and move the enemies into the line was satisfying

I like the powerup cards and the use of the theme. For me the sword felt weird to use as it would get stuck in one place and I was able to collide with it. Other then that great game.

I won't lie, this would be a great game with sfx. I can see so much potential in it. Limiting your controls to the mouse tho might not be a good move, especially since reading your replies you want 5 powerups. Common mice only have at most 3 buttons. Aside from that I love how the dash felt.
