Thanks for playing, I'm really glad people can figure out the last level it's my favourite!
Getting the pacing right is hard and I agree it's not quite right yet. There are a couple of delays (particularly the platform coming out the tube) that aren't supposed to be happening. The pause before the next level button comes up is while your total score goes up, it's in the bottom corner and I think easy to miss so it looks like nothing is happening. Should probably be on the main stats in the centre of the screen. Pacing will definitely be a focus if I develop this further after that jam!
