So I played the demo. The game has great visuals, effects, physics, music, and it's nice they put multiple levels of difficulty in. The only problem I see with Block Man's stage is level design. For instance, the chase sequences are not well put together. There is a narrow spot you have to jump through, and every time I naturally jump it would push me back. You have to press forward to jump through that narrow section, which is dumb. Not to mention, I found myself in a glitch where the chase sequence just continues on and on and on.
Another problem with the level design is the forced use of the speed gear. It's actually quite difficult to time precisely to jump on falling blocks, even on Newcomer Mode. In the section where you need to jump on blocks to traverse upwards, enemies would spawn after you hit the second level. This is annoying because not only do you have a small, moving platform to work with, but if an enemy hits you, you practically fall to the first level with pits which most likely causes death.
I can already tell X has better level design, which is a little disappointing. The price tag is right, but I'm going to wait when it goes on super sale unfortunately.
