Neat game.
A few nitpicks though, the camera feels too close for the speed of certain bullets (the homing ones when they're at their top speed and some boss ones that have a rotation around the boss as part of their movement when they get far away from the boss). This also makes it hard to see where some bosses that moves a lot are.
Also, I kept getting stuck planting a tree without this pausing the game while trying to harvest trees. This either needs to pause the game or be put on a different key imho.
