This is a great game - one of the best ones I've played so far in the jam for sure. I found it quite difficult starting out and I really didn't get very far without getting several upgrades but then things got a little easier. I really enjoyed the environment you've created, with the lighting and the graphics you used. I thought your menus were well put together and the polish you've added to the game wasnt unnoticed by me. I think there are one or two sound effects missing (like firing and enemy taking damage/dying) and the damage could be reduced a bit at the start to make it more noob friendly, but these aren't huge considerations. Overall I loved it, so good job team.
