2.0 is a HUGE improvement to the character. He feels a lot more maneuverable, and the additions to the moveset in Shotgun and RL make it a lot easier to run and gun, which feels more faithful to the Slayer's playstyle in his games. His new sprites and animations add a lot more to the character, and he no longer feels as stiff or awkward. Great job!
I did notice his Spring and crouching sprites are still the old ones, which look really janky in comparison. Also his weapon menu feels hard to control, at least with a gamepad - and speaking of which, dashing seems to send him at a weird angle if holding forward.
I somewhat lament the removal of the Meathook. While the old version wasn't particularly useful, an ideal version of it could make for a great traversal tool if it had a good range and if the Slayer could jump out of it like in his game - possibly leading to some unique options in zones like DSZ or ERZ.
All in all, the character feels a lot better to play, if slightly cumbersome at times, at least with a gamepad.
