The best SFX and the mouse hover detail effect in this jam. Classical 2D shooting game. But you add more features such as add some bonus(level up) after each level. I am very likes your game. And Your thumbnail is fantasy. I am starting following you. Very nice.
(In some corners, the projectiles bound not very natural, looks like move horizontal. And You can add more UI on the gameplay such as remainning enemy or score. Otherwise, player cannot know when to win/end the level. Hopes you can rate for mine as well. )
