Great job with this! I agree that it does function very well as a fun arcade game. The music is great. I had fun playing this for a while even though I don't play these types of games much, because planting seeds made it easy to regain health. The axe enemies are a nice addition to the game, and they tie the theme together. I also really like how doing the area attack pushes the axe enemies away. I would've liked to see a little more of an explanation of the vulnerable tree species in-game, perhaps as cutscenes between waves of enemies? If you were to work on this further, it would be super cool to have multiple waves of enemies, slowly introducing different tree types or other attacks. Really nice work overall!!
