I appreciate the feedback. In terms of input I intended for this game to be played using a controller but I didn't have enough time to switch over the tutorials with a controller, or to implement localisation for both input types. I was thinking of making it controller only but I realised that maybe some people won't have a controller.
In terms of the survival elements to it as well as healing, I appreciate the input. I am actually expanding the game and will definitely take this into consideration.
Thank you for playing and thanks for the feedback!
