This is a game of skill, and I am quite rusty to get used to it. Especially the movement mechanic is completely different from most First-person shooter game I've played.
The player movement feels really heavy and sliding. It is good in some ramp or big area, but it is not good at all in making a simple jump to another platform.
The difficulty curve in this game is fine, but I feel like there are not too much fun because the lack of easy levels.
Nicely done. This game does look nice.
