Here goes my 60th and final vote this LD. Some feedback.
Using mouse movement for both movement and cards is not an idea I am very fond of. I think the cards could be just bound to 123 keys and that would be fine.
Mouse sensitivity was through the roof and while I managed to play for 20 minutes, it was an issue for me. Full option menu is not a priority during the gamejam, but any kind of control over that would be gold.
I would love to see my stats on hud, as I could not tell if the cards gave me any boost or what.
There was also one part zombie who just wouldn't die. When I clicked it, no shot was fired, but blood splash would show up anyway, and it would not damage it as it never died.
At some point I managed to figure out the objective, but it would also be nice to have the hud tell me what to do. "Retrieve car parts from the zombies 0/10" -> I retrieve a part -> "Bring the part to the car" -> I bring the part -> "Retrieve car parts from the zombies 1/10".
These are the basic things I feel are missing right now. Other than that, well, I did play it for 20 minutes even being unable to finish it, so it is pretty enjoyable overall I must say. Keep up the good work!
