Spot the Two Differences

For CaptainSparklez. Spot the two differences among five blocks, eight builds, and... a surprise at the end.

I decided to make this map after seeing CaptainSparklez's recent (as of 1/3/2019) videos on Trevor's "Which doesn't belong" and CommandMC_'s "Odd One Out".

The premise and rules are the same as the previous map, but the gimmick has changed.

In the first section, you must choose two blocks from a selection of five blocks that are different from the rest. The difference can be tricky, so try your best to think of all possible differences before choosing!

In the second section, you must choose two blocks from a selection of three blocks on the left that relate to one of the two blocks on the right. In all, you are selecting three blocks.

In the third section, you need to check all eight builds to see if you can spot what is off with one of them. They will all be identical in all ways except one, and by that I mean: one block is different. Press the button for the build that is different.

In the fourth se... now that would be giving too much away.

Any wrong button press gets you killed, however, there is a half-way checkpoint that sets your spawn.

Have fun and if CaptainSparklez is reading this: "Good luck, Jiudshauoygdwqboiubfoan."
