Thank you so much for playing!
I didn't wanted to add more indicators on where the projectile is going to land, I wanted it to be more experimental and experience based. This with some audio cues would be better hehe but I didn't had much time.
And the granade/mine fly much more than the rocket so they can reach where the rocket can't. Deal less damage, but have more knockback
There's definitely areas to improve in both points you're saying, I just wanted to explain ^^ I really had fun making this game and I'm glad you enjoyed playing
