Game looks and sounds really good, overall really professional!
On the gameplay-side the game can get quite frantic quite fast, and juggling tools and setting off fires is pretty funny gameplay-loop. It does get quite difficult though after first wave, with the amount of fast projectiles and all.
I think one thing that would really ease things out on graphical presentation: The bubbles indicating what tool is needed could have been placed differently, as you need fewer steps to see what is needed on the bottom than what is needed on the top etc. Having each bubble be more aimed at the side where the player is would be a nice quality of life upgrade imo.
