Hey there!
Visually, this is the best game i've played so far. Congrats on making it 3D!
The gameplay is interesting, but the different weapons and the spread shot aren't balanced enough in my opinion. The sounds are also incorporated very well. Unfortunately, i don't really get what the goal of the game is. And how did you incorporate the word "Oh"?
A lot is unclear, especially with the in-game tutorial xD.
But with some changes, i could imagine this really well as a horror-game somehow.
All in all, fun game which incorporates the limitations really well! Well done! :)
