Very enjoyable, but short! I wish there were more levels to it. It is a pretty interesting concept.
I think that holding "Up" while climbing the ladder shouldn't make you climb back down! Usually games make you hold up to climb ladders. Your game lets you just tap once, which is great for the type of game it is. But I instinctly held up and found myself climbing up and down repeatedly! It would be better if you had to press a different button to go down.
Also, it would be better if the text moved faster, but required you to press a button or wait a second before moving on to the next line. The way it is now, the text seems super slow, but then when it reaches the end of the line it basically instantly starts writing the next one. This results in the player having way too much time to read the beginning of the sentence, but not enough to read the end! Which is a shame, because I love the text you wrote.
It's kind of weird that you can move during the animation of the character using his time rewind thingy, but that's a minor complaint.
Overall, it's a solid game! I made a lot of complaints, but that doesn't mean I didn't like it, far from it! It's very good and my complaints are pretty minor. Good job!
