Hey, thanks a lot for playing and for the review! All of the things said here have been noted down.
During development, I did purposefully make it hard for enemies to shoot themselves as I thought it would make the game too easy. However, I now see that was a bad descision and the game would be more strategic and improved overall with more friendly fire.
A life bar or some other hp indicator, yeah that's a "whoops" on me. It was planned, but I made some poor descisions that cut off time to make it.
Finally, I'll play around with the balance of projectile speed and player speed.
Once again, thank you very much for playing and the review. I'd love to upload a new version of the game once the jam is over if I can, cheers!
