I've just finished playing V2 and I was almost left with nothing to say as I just really enjoyed playing and wanted to carry on, but I do have a couple of things I enjoyed and didn't enjoy so much, which will hopefully be useful:
- The presentation and level design is really immersive and good looking, the minimalist style works really well for this game
- The tutorial level (or first level) I didn't see any UI on the screen to help me get started, so it took me a good minute or 2 to get started
- The last level stumpted me for a bit, the slight change in design confused me initially, for example the particle effects, I wasn't sure if they were visual only or if they attributed to the gameplay.
- One thing I'd really like to see when I complete a level would be a UI screen that tells me how fast I completed the level
I really cannot say much more, it's a really enjoyable game that is easy to get addicted to, just needs more levels at this point!
