Is there any way to deal with the mouse acceleration in game?  I really wanna like this game, but the inability to point my cursor where I want it to go is proving to be a game ruining experience for me.  I've lowered the sensitivity setting down to like 30% and tried adjusting the tile snapping setting to minimum and maximum, but nothing really fixes the issue.  In fact, as far as I can tell, with the tile snapping setting on, the cursor attempts to lock onto a tile when I press LMB or RMB, but the mouse acceleration causes it to fly right past the tile making it even harder to aim at anything.  

Is it supposed to be intentional challenge?  Is it some weird setting on my computer?  I'm just baffled by this issue.

Ah, that's a personal preference that I should have made optional, sorry about that.
I like it because I find raw mouse position looks really staccato and I tend to home in on a target gently with the cursor, but I appreciate that if you have high FPS skills you want to be able to twitch the mouse to the precise point you expect it to land. Give me a day or two and I'll add a toggle!

I've published a quick update adding an "Aim smoothing" toggle so you can turn this off if you prefer.

Yeah, that feels a lot better for me.  Thanks a lot! :)

No problem :)
I'm sure loads of people quietly felt the same, thanks for calling it out!
