It looks and feels like a game from the mid 2000s. It doesn't perform particularly well, and there isn't anything technically impressive about the game, especially considering it's been on the go for almost 15 years.
Another example is Blender, it's a bit hard to grok, but overall does the job extremely well once you get over the warts.
Even in terms of fundamentals, this game is a little... lacking. Default controls, graphics settings, UI, animations are all very early-noughties (that's without commenting on the quality of the artwork, it's actually quite a nice style and some of the assets are cool), things have evolved hugely since then.
