Nice job on the art and boss mechanics. Quite a menacing fruit bowl. I thought I found a sweet spot at one point but it only lasted a few seconds. I'm awful at these games so I knew I didn't stand a chance. It'd be cool to have some pickups or powerups around to change mechanics a little and encourage the player to move around a little more. Some sound effects and music would also go a long way.
Godot was giving me a looping error when I tried to reach the boss on the right. It would spawn the bullets only and no boss.
