Firstly, thanks for playing and many thanks for the valuable feedback! Definitely agree with regards to the lighting on some of the scenes at the moment, been non stop tinkering with it and still can't find a happy medium. All a process of trial and error :p
Yeah, the collision is still proving a little problematic at times when the ball hits higher speeds, causing the ball to fire off unpredictably. Mostly reproducible and stuff but I'm struggling to find a working fix for the tile seams at the moment. Auto ball reset on fall is already fixed, simply a matter of tagging the environmental objects correctly. Just a total oversight on my part, my bad! Oh, that hole variant has a ramp on the back to get up to the hole by the way, just the ramp blends in completely with the floor color and it's hard to spot unless you're near it with the light on, or the camera's in motion and catches it at the right angle. Byproduct of the poor lighting you mentioned, apologies!
Haven't the slightest clue what could be causing the input lag though, maybe that my input is handled in Update() come to think of it, were you having frame drops or anything?
Definitely looking to source out some decent sounds and the like soon, despite my proficiency on the audio side of things being a little... inexperienced shall we say :D
Again, thanks for the feedback my man, much appreciated, glad you enjoyed the visuals!
