Hey there! Thank you for trying my game! Thank you for your thorough feedback as well!
The physics interaction desync is definitely taken into account! The pressure pad can be used by the Timmies but for some of the levels, the boxes are meant to be there as a blocker as well (which may make levels a bit harder!). I didn't want to remove physics all together since I figured the interactions are pretty good fun but its definitely something I will look into in the future!
Thanks for the comment!
