Hi, first of all i think the game is pretty fun compared to its current stage, and it will be interesting to see what it would become.
Here are my main issues:
The player is way too slow and feels too heavy.
The machine gun doesnt have a sound, and the player is still being rotated even while controlling the machine gun.
Also the advanced options button doesnt do anything
Things i liked:
The sfx are nice.
The weapons feel good, including the machine gun (that is missing sound).
Destructible objects are an excellent addition.
The game has a long way to go, but i see the potential. good luck.
