Thanks for the feedback, the camera was very problematic because we decided not to give the control to the player, we want to iterate on it more and give options to control the camera with the right stick, as for the medkits the intention was to be a surprise to the player, but with some kind of indication on the second try with a glow or an outline.
The melee collision system needs more interactions, it's totally based on the animations, and sometimes the sword enters the ground, for games like this it's better to make hitboxes like old school beat'n ups, but is a nightmare to fine-tune those things :).
But it has been a great learning experience, and we pretend to work more on the game.
