Fun little platformer - I really like the dashing mechanics, since it freezes you in the air, you can do a lot of fun things.
And the boss fight was really fleshed out, great job!
I think some hit feedback on enemies would be great, (also that bug where you don't actually die is funny) but that's about all I have to comment on.
Would love to see you come back and add more after the jam, thanks for submitting!
