Don't need to repeat all the positive things other people did :P
Flame thrower feels like its unaffected by the player's velocity, this makes it feel "Sloppy" like skating on ice, but with a flame thrower to me!
The counter above the player's head is oscillating all over the place for me (possibly 144hz monitor problems) - it's very distracting.
The controls here scream for WASD alternative inputs - it could be a one handed game no problem! That's a good thing!
Good to see Phaser getting used too - its a pretty agile engine.
Good jam!
