Thank you for playing my game, I agree with your point on the upgrade system, I wanted a system where once you killed a certain amount of enemies, you upgraded your gun style, so from pistol to shotgun, up to assault rifles, possibly a mini gun, would need to scale the enemy drops at the same time or ammo would go in the blink of an eye. But I didn't have time to add that and also didn't want to force the player down a gun play style route they might not enjoy. I could possibly have another stand or maybe interact with the sleigh to change guns once you unlock them. Definitely want to add more to this game in the future, won't be a full game but a few extra features and some balancing would be nice to add.
