Ok, I just beat the final battle, so I'll give it my review. First of all, the training is fun. When you can't beat a level, you can just train for a couple of minutes and win. The missions distract you from focusing only on progress and add much more fun to the training. The museum is a nice feature because it allows you to get money while afk. It is also great because as you progress onwards, you unlock more things which give you more money via the income. The arena is pretty cool because it is nicely designed and as you progress, the level names become cooler. The home build thing is pretty cool, and it adds a nice feature. All in all, a great game and I can't wait to see SoulGame's next project!
in my opinion, 2-x was harder/more frustrating than 3-x, but both were hard. just a tip, on fast clik areas, use left mouse button and right mouse button, itmakes th game so much easier!
Thank you for playing! :D
