Hey there! No, there isn't any such thing, because the sequel is a separate game, with its own different story and systems. The main difference gameplay wise is that in the sequel, instead of having your skills determined by the class you chose, you can pick and choose which skills to learn and equip.
Hi, there should be a "Synch Monitor FPS" in the options, please try toggling that and see if it fixes it (you can use the mouse if keyboard is too fast).
The issue is caused by the engine I used processing on a per-frame basis under the assumption that the game runs at 60 FPS, which means that if you had a monitor that could run at say 120 FPS, the game might run twice as fast. The "Synch Monitor FPS" should be able to fix this and force it to run at the intended speed.
There are no plans to upload this to steam, because doing so is expensive, and this is admittedly not my best game anyway.
