Very interesting.
Reminds me a whole lot of Autumn War: Survivor. You have an interesting control interface, being able to slide and shoot, wallclimb and all that. It makes it awkward to shoot, but it certainly makes it feel cinematic. However, much like Survivor, the controls and gameplay feel extremely sluggish, and Pico is really floaty when you're trying to bust some ass.
Graphics, sounds and such are alright, as are visuals. However, there's times where the AI does very stupid stuff like go the long way to find you, or quit following you because you moved two feet. This made a lot of levels really, really, stale rather than intense like I was hoping for.
Most games have upgrades and MOAR WAPONZ. This doesn't. Which compounds the pretty shoddy gameplay. You could do some very simple tweaks and have a playable, action packed game. Which would be awesome.
