There may be a problem on low-spec computers concerning collision when landing on blocks. Players seem to be going a little bit through the block when landing on one, and quickly bounce back up as if the collision is handled too late. This may cause some problems if, for example, a kill brick is placed underneath it as obstacle.
Here’s a video of what one player has noticed to happen:
Now this can indeed be fixed by increasing the height of a block or moving the kill brick lower, but those are solutions to evade and workaround the problem
I think this may have something to do with low-specs computer being slow to handle collision in the client, and hence the player will very shortly fall through a block before collision is detected, and being placed back up.
Simple fix for that specific problem:
In the touch script, make it ignore HumanoidRootPart. It has weird collision when landing, to fix the previous problem of legs and sometimes the whole body clipping through bricks when falling from a great height.
Side note: I heard MIDI music in that game. Please update it omg lol. I had midi music playing in 2 of my older games until I changed em to mp3 a year ago.
