Wow thank you so much for such awesome feedback!
Your nitpicks are 100% right, the slingshot would be better yes, i honestly never play these kind of games so i never knew. An option to switch aim or sling sounds like a good idea. The propel meter issue is so on the dot! It definitely needed more indication! something like a particle fx or turn blue to contrast. Good feedback thank you so much and im glad you liked it :D
