Oh I'm a fan of rocket jumping! Was fun and the the music is sick!
Did you experiment with making the knockback based on the the distance of the shot target? I bet that changes the feel a lot. Could be a different character or something.
Nope! I just did a impulse based on if a shape cast hit or not. It may have been more interesting to reduce the recoil if further away. I will probably try it out if I have some free time :)
