Thanks for playing and thanks even more for your feedback! ill take a range indicator into consideration its going to be slightly problematic to implement since lifespan of the bullet is based on time currently but I should be able to change it to be based on distance from player global position then that would allow me to know precisely where the bullet will stop and I can make some type of indicator. I plan to implement armored enemies as well as enemies which split into multiple smaller enemies when killed as well as some others. As far as the shield goes, the stutter may be due to web based play (assuming you played the html build) but I do need to look into optimization either way.
