Ok, so: that was great! It was both rewarding and instructive watching your video.
You wish there was a "medikit indicator"... Well, there is one - kind of! :D I preferred to keep the hud pretty clean, but remember that you can always pause the game and check your inventory by pressing "P" (you never did it, if I'm not wrong).
About the "quantized" ammunitions (you collect up to three bullet, depending on your free slots, and those in excess are wasted): I thought this was a fairly standard mechanic. Deciding the right moment to collect a new ammo pack is part of the "ammo management subgame", isn't it? :D
If you have any suggestion, however, I will consider them very willingly!
Also, you think it should be clearer that a ghost is hurting you in the graveyard? I didn't think of that, but it's an interesting idea. I'll work on it. :)
Last but not least, if you're playing again, I would warmly recommend to download the latest version - with bugfixes, improved features and a brand new ending in addition to the existing three.
Thanks again for your time and your tips! :)
