Good game play loop and is very engaging!! Music was pretty fire. Movement is smooth.
Now for the bugs:
1. Once the coins are in the sand, I will have to pull them back on the grass and then collect them... Though currently I don't see a point in collecting them.
2. I couldn't figure out how the guns are place as it occasionally works, when I click on the ground and sometime it doesn't.
3. Couldn't pick up ammo and deliver ammo. Overall the E and Mouse key respond when they want to. I think it will be easy to fix. So please look into it once.
Other that these bugs, I feel the game is visually very polished and the enemy designs are pretty good.
Kudos!!
