This game would be even better if you gave "bonus" gold for the time remaining when you win a battle. You can easily screw yourself in later battles if you don't purposely hold back in the beginning battles and kill until the timer runs out. Other than that, it's a fun game.
Wouldn't be too bad of a game if the weapon switching buttons actually worked. Often times I'm left with nothing but a pipe even though I have ammo for my guns. I thought at first I may have been pressing the "melee weapon" button, but I was pressing the correct one. Fix this and it might be worth playing. As is, it's way too buggy with weapon switches.
