Coachgun feels way too overpowered right now. It is readily available in stores for dirt cheap, having excellent accuracy, speed and damage. Even more, equipping two large bandoliers gives you a whopping 200 bullets. The regular flintlock pistol becomes even more useless as it already was. Maybe change the coachgun to a single shot musket and balance the stats to complement the already existing flintlock pistol. Later on in the game there are better weapons available, sure, but as it is there is no need to use any other weapon early on, as the coachgun simply destroys anything low-level.
The weapon model itself feels very modern and a bit out of place as well.
Regarding the Skyclad, I love the idea behind the armor but it looks silly. It feels like I'm wearing glowing pyjamas, it's hard to mix and match this armor with anything.
