Where to begin with this one? It's a fairly unique game that takes things from various genres.
During the day - You place traps in an overhead view of the surrounding buildings you're meant to protect. You can go to town and shop for a new gun/axe, buy some potions (beer), and buy ammo. There's also a church that can bless some bullets or your axe for a fee. You may also upgrade your character with skillpoints gained from levels. They range from using your gun better, having more stamina/health to upgrading your traps so they last longer/do more damage. The trap upgrades are generally visual upgrades too.
The enemies come in waves and each have their own path and target to the building shown. It even shows you the route they are planning to take to get there. Most damaging traps do not go off on their own. They are not place and forget for the most part. The automated ones generally are meant to slow down the beasts instead of kill outright. Placing a hanging net for instance (with which rocks are on top of) can only be deployed by shooting at it from a distance. To get the enemies to stand under it, however, you can place bait beforehand. They'll stay there and eat it until done...or die from your trap. There's also a spike trap that DOES go off automatically but only if 3 or more creatures are standing on it at the same time. Grouping the monsters together and making sure a lot of them go toward 1 bait/trap can be achieved by using a "fire wall" that blocks whatever path you so desire. The enemies that were going to head that way will now go a different route (the path will update as well) to their target building.
During the night - You run around in 3rd person with your axe and musket. Before each new wave begins you have about 10 seconds to get into a better positon for the oncoming attack. Later levels this is important because the next area you might have to defend could possibly take you over 30 seconds to get there even if sprinting. Using your axe in melee combat is fairly basic and you can build up "rage points" that let you do special attacks. Using the gun, however, is difficult because this is the early 19th century. These guns are slow and take quite a while to reload....and you have 1 shot. The only way you'll be able to reload in combat is if the enemies are very far away or you have a greater fear factor than they do. Enemies grouped together (even weak ones) will not fear you (despite how manly you look). Alone, however, they will hesitate to attack you and the game shows you how long before the next attack. They also are afraid of bonfires (which you can place during the day) that you can light to give you a boost in fear temporarily. Then you fight through each wave until you're finished and it begins again the next in-game day. Failing a night will happen if some monsters end up destorying a building. It might sound simple, but in actual practice a fair amount of thought will go into your planning stage each day and then everything must work out as you hoped during the night...
Beyond that, the story and the music's alright, nothing to write home about. Certainly could have been improved but it did the trick. Voice acting is okay too. Not great, but it's decent enough. The graphics fit the bill as well, but no more. The art style and UI was great and stylized though. The only other complaints I have about the game is that it's just not as polished as I would have liked. It's an indie game and they did great work, but preformance was just...all over the place for me. It never ran very well. That and sometimes the steam achievements didn't work. This is a known issue, but no fix for it. People are still talking about in the community hub forums.
To wrap this up - Amazing game with great premise and I really hope they're going to make a 2nd game. This is supposedly "Tome 1" so I hope there's more....especially with that ending. If they can learn from this game and improve upon it in the slightest I will be right there waiting to give them my money.
