Oh! Understood. 

A couple more things I remembered after playing a little bit more today; maybe speed up the kicking animation as well as add the stun effect; the melee option I believe is vital to conserving ammo. 

On that note: perhaps consider having a single ammo clip/grenades etc. completely restock the weapon/item. I know the whole leaving and entering the room item respawn "mechanic" is memorable in the context of the original, but just like there it can be monotonous. That is unless your goal is to totally preserve the over all game feel of the OG, which I understand. 

Thanks for being open to suggestions, and thanks for the service to the hungry Metal Gear fans like me!
