Game looks and feels great to play, especially for a jam! Simple, but fun.
I'm not sure if it was intended, but you can purchase the mini-gun without having the score for it. Having no notification that you're reloading, or having no notification you're being hit made it a bit confusing at times.
If you plan on taking this game further, I would suggest adding more portals, more artifacts to defend, and a more robust shop system.
