Damn this is difficult! Love the style and the sounds, what did you code this with? Think it would benefit from more progressive difficulty and introducing the different types of enemy more slowly. Oh and some in-game music.
Totally agree - I did want to balance it more, but ran out of time. Hopefully, I'll get the chance to add some more baddies and make them attack in waves.
BTW, it's made with Phaser - definitely recommend; easy to get into with great docs & community
