This game is really good. However, I find some places to be quite frustrating. One of them is the hitbox area to take down the enemy. I sometimes just can't take them down by sliding into them sometimes. Another thing is that slow motion actually does not slow down the stopwatch at all. So having slow mo won't actually help in speedruns. Also, perhaps have a hotkey change option for players who enjoy their own button style. One other thing is perhaps have more tutorials or information that helps new players understand what they can do and whatnot. It took me some time to learn how the game controls, weapons, and enemies.
Conclusion, I say this is a great game and while there are some bugs or problems with physics, it's starting great as a game
