Very polished well done! I had this concept in my head but our team chose to go for my farm game idea, I'm glad we didn't go for this concept because what I had in mind for the game was so trash and boring compared to this, you executed it perfectly and way better than I ever could, I'm shocked!
The UI is amazing, the SFX are nice, the difficulty is perfect for me, and that art is utilized perfectly! But there are some things I don't like such as, being hurt by my own fire, also sometimes it's not clear where I'm shooting, or which tree is effected by my fire, its until I am really far away from the trees I thought I shot is when I realize I didn't, driving diagonally would be nice too!
Despite all of what I said, I really enjoyed this game, it's very well done and polished for a 48hr game jam, great job and good luck if you're willing to update it later on! :D
