This game is challenging, and entertaining. Sadly, certain technical aspects that should be taken for granted are not there. The game needs to save your progress, and also needs a pause button. If you add these features, I'd give this game 5/5.
Enjoyed it, but it was a cake-walk. Never without a weapon, melee weapons are infinite use, the "L" attack was broken, have to be hit 15 times to lose a life. And health was everywhere.
