Castle Woodwarf 2 is a Kongregate refugee soldier defense game (soldier defense being a dumbing down of tower defense games where you just build soldiers to combat the waves of enemy soldiers). There's some lightweight resource management as you have a cap on units and you also need to allocate some of your units to gathering supplies and gold, but this is a very shallow addon to the core gameplay. Unlike traditional TD's, this is shallow and linear, there's no strategising about where to put towers or worrying about enemy pathing because enemies attack on only one line. Yawn.
This wouldn't fare well even as a mobile app (I checked, it doesn't look like it's on app stores).
One important note is that even though this is an amateur project, it does seem to be sincerely and genuinely made. I couldn't find any flipped assets, plagiarism or any other kind of insincere actions from the developer, but unfortunately genuine intentions alone are not enough to produce a brilliant PC gaming experience.
From a technical perspective, the game doesn't meet basic minimum requirements that most PC gamers expect as standard.
A choice was made to use obsolete, decades old retro pixel "art" as a substitute for contemporary PC graphics. It's unclear if this is due to lack of budget or talent, regardless, the overall visual quality of the game is extremely low as a result.
There's no option to change the resolution and no useful graphics tweaks. There's no way to ensure this is running at the native resolution of your display. There's no guarantee this game will look right on any PC as a result of this hamfisted design decision.
The controls can't be customised, which will be an annoyance for many, but it can also render the game unplayable for differently-abled gamers, left handed gamers or gamers using AZERTY or other international keyboard layouts.
These technical defects push this game below acceptable standards for any modern PC game.
Reviewing SteamDB to check how popular this game was with players reveals a surprise... there's a modest spike in player counts for the game. But this only happened once, around the same time that trading cards were applied to the game... so this is just card idlers getting their cards and moving on. A closer look at the numbers shows the game just has a couple of players every week running up the game and idling it for cards, then deleting it. We must ask how it benefits gamers for there to be so many games like this, with no merit as a serious game, that only generate sales from people idling and selling the trading cards.
So, should you buy this game?
Castle Woodwarf 2 has the gamer gouging price of around $7 USD, it's not worth it given the defects and shortcomings with the product, especially considering the sheer number of completely free, much higher quality games on Steam. This is also competing with over 11,000 free games available on Steam, many of them far better than this paid product.
