Not even a game

If someone already played my "not even a game", you'll found out there's no much content in it.

• The main issue is that I made things too complicated, I tried to create a weapon system and inventory system that can reuse by any character for example like player ,enemy or NPC. Luckily it didn't had much bugs, but it still cost me 5-6 hours.

• The second issue is
  in second day, after I finished modeling and rigging my character, and I import it to Unity, in the engine the rig is totally broken
  the bones had weird rotation, I check Blender there's no problem with the bones ( after jam over I found out that it cause by I used the pre-made rig, and it already had bone rotation issue D:  )
  I spent a lot of time in Blender try to fix it, after 2-3 hours I suddenly remembered that Mixamo can do auto rigging, so I just yeet my model to Mixamo website, and it fixed... I wasted almost 3 hours.

(wtf is this rotation)

(finally fixed)

• The third issue is the IK system, because of the character rig problem, I also  rewrite the Aim system (which using the humanoid IK function), and wasted another 2 hours
  end up found out Unity has a new IK system, I just need impot package and attach script to gameobject, it only take 10 minute lol

BTW this is my second jam, I'm still not used to develop a game like this way, but I enjoy it :)
