I like the idea maybe with a bit more polish it would be a great game I feel like when the player dies adding an input buffer on respawn so the player can not dash into a fire as soon as spawned in would be cool also adding a death animation maybe a roasted marshmallow doing a Mario like death or something, last thing some of the music is quite good but the loops are very noticeable and harsh maybe add a fade in/out but all in all great work.
(ps some of the times the dash did not break the blocks but the double jump helped me out a lot :) )
