Hey, looks like you were really onto something here! I like the idea of FPS / horde situation, and the scenery was cool!
I couldn't quite figure out how it worked, though. A description of the controls / gameplay would have been very helpful. The cursor not being locked was strange -- most FPS games should lock the cursor and only unlock it when the inventory is visible. Interacting with pumpkins with the UI was strange - an "interact" key press would've felt more natural.
Overall good submission! Keep making games! :)
