Thank you for the feedback and for playing the game.
I will address the stuck and bump issues in the next patch as it should be easily fixable with some adjustments to the player's colliders. As for the flares and rockets restocking I agree this is a cause of annoyance especially with the rockets as you need to backtrack to restock them, I will also address this issue in the next patch.
Hopefully I can get the patch out quite soon to address the above as well as fix some minor issues I have discovered in the past few days.
