Cool idea checkpoints would of been appreciated since it's pretty difficult. As with several of the other mouse control games it's really easy to click out of the screen and cause mess-ups especially in this game since space scrolls the webpage.
For this game specifically I think an option to lock the start of the vector to the center point in the screen to decide where the mouse click direction was would of worked out better since you occasionally would screen wrap and then have to move the mouse too far to fire the way you want to.
There also I think was some bug(?) with the animations not displaying right (The bats specifically looked kinda weird like the sprite was shifted on the sheet)

The shifted sprite is a weird artifact from the low aspect ratio. I tried forever to fix it but it just would work for some odd reason. and sometimes it isnt there. Also this game was originally (and still intended) for download/desktop only. I only added it as in browser after the fact for people that didn't wanna download it.
