We reviewed this game as a group in our Games Design class and I thought I'd share our criticism.
Firstly, the game has a fitting theme and seems like it has potential.
That being said, there's a number of issues we highlighted:
-The AI can sometimes struggle to pathfind to the player if there's boxes between the player and enemy.
-The pause menu is a slight confusing with there being no resume button but there being a play game button, it caused a few of us to accidentally reset.
-The UI needs more visual aspects rather than just numbers (like a red outline when low on health or maybe the ammo number glows red when low)
-The game is brutal, and idk if that is a design choice. I would guess this is intentional but the health packs are a bit too rare.
-More varieties of armour please
-The numbers in the game are not very clear what they do. Like what is "+2 defence"?
-You can melee objects through the corners of walls diagonally (like if there's two map squares with gaps on either side diagonally and there's a chest in one of the gaps, you can melee through it).
I hope this helps you in your future development. Thank you for the experience!
