The game looks great, and is undeniably polished in different aspects like the menus and inclusion of multiplayer. I, however, do feel the gameplay is a little lacking. I didn't know if I was doing things correctly half the time, especially at the end where I vaulted over the entire tower instead of climbing the stairs. The mechanics felt like they were unintentional or buggy, and there were certain odd things that happened like enemies instantly killing me with health upgrades.
Please don't take this the wrong way though! I only want to bring attention to these things because I had a lot of fun playing this game. It's incredibly impressive and well made! I look forward to replaying it with my friend sometime soon :)
