I like how the enemy has different attack patterns that have very different feels to defend against! This adds good variety to the gameplay and kept me engaged. The laser beam attack needs a bit more of a "charging up" warning so that I don't get blasted in the first moment of the game (although sitting in the laser after getting hit and shooting is a great way to get a lot of damage on the enemy haha). The stars were fun to dodge, but they last for a long time and the enemy isn't there to be shot for the whole time. My favorite attack pattern was the finger guns, because I could create my own opening to shoot at the enemy while also needing to dodge the attacks. I was sad when I defeated the boss but nothing happened!
The music is nice, despite being a little loud.
The game window is very small (a tiny little world, indeed!), and the UI doesn't expand when making it bigger, but it's not so small that it's unplayable!
Overall, I enjoyed this and think it has a lot of potential! Great work and congrats on submitting!
