I believe this game only has one stage? After I defeated the fish boss, it just kept on scrolling, so tell me if there's more that I missed.
The first thing I'd like to mention is the control. The mouse based movement is an interesting idea, but it is also very imprecise as slight movements of the mouse can get you killed. I'd suggest an alternate control scheme of arrow keys and Z to shoot.
The idea of "conservation of energy" made for some challenging gameplay, except for the fact that you can collect 1 energy, start firing the 3 sets of bullets, and then as long as you don't let go of the left mouse button you can continue firing 3 bullets even if you're out of energy.
The boss fight was fairly challenging and had some varied attack patterns. You've made a good start!

Yes, there's only one stage. A cutscene is supposed to happen before the level and after you defeat the boss, but it broke at the last minute. I'll add a note about that in the description. I apologize for the confusion. I'm glad that you find the mouse controls interesting. I was wondering if it would be better to use the arrow keys instead. The original idea was to have the mouse scheme for a mobile option, but I won't be going that route. I'll change the keys to what you suggested.
I noticed the infinite amount of energy when you hold the mouse button, but thought that it would be a nice little "cheat" until I got some of the other bugs fixed.
I really appreciate you playing this little game of mine, and offering your feedback. It was extremely helpful!
