Hey, sorry to hear you've had trouble with this section. Unfortunately we're not quite sure what the cause is... some high-end computers struggle to run it, some low-end computers handle it just fine...
Whatever the case may be, my best recommendations would be to use mouse-click controls, play the game windowed and shrunken down, closing any other intensive software you might have running in the background, and making sure you're playing the v0.204 build.
If you need to update your game version, the save file transfer guide included should help make it so you don't lose any progress!
