it's an okay game
It works as it is, but I have two pieces advise: Give more than one weapon point per level; right now one only gets enough to fully upgrade one weapon, and by upgrading the sniper rifle, one does not need any other weapon.
the second advise is: remap the reload button; it's al well and good that it is easy for you to find it, but on my keyboard that button is an 'Æ' and is located over by the 'return' button... it cost me a couple of tries to find that out. Since there is no need to change away from sniper rifel it was okay, but annoying that I could not find it without pressing every key on my keyboard.
