Thanks for the feedback. I am adding crouch, I actually just forgot to make the animation for it lol. I definitely will make it so the jump feels heavier, right now its just a basic jump that has no feel for it, as for the effects, i think without effects no game is good, I was thinking of adding sparks whenever it hits a platform, whereas something else when it hits a player.
Also great reference, Ive played pocketTanks before and its a fun game, ill try to incorporate some of the features that i find fun.
