This game is beautiful. It has basically nothing to do with the xkcd comic it was based on aside from "Bobby Tables" (unless there's something at the end I missed), but the platforming and table-using mechanic is still great.
The "tutorial" is well designed--first you show movement, then jumping, then checkpoints, then throwing tables. One step at a time. Nice job. :) And throwing tables is really fun (even if they do go quite far, which doesn't pair well with the camera later).
But the level after the second checkpoint (where you have to hop on the two brown cubes) is a few steps above what you've introduced to us. You show us our table mechanic right before that level by having us put down a table and hop on it to get to a higher ledge. That's fine, but right after that, not only do you introduce enemies, you introduce an area where it's pretty much necessary to put down a table just right (and possibly drag it [trying not to die in the process] because the area's a tight spot), and do jumps exactly correctly on tiny cubes! Next time, please increase the difficulty one step at a time, not three steps at once.
The cat killing is pretty brutal. And it isn't made clear that the cat is an enemy, since it's just as colorful as everything else and looks fine from a distance--I went right up to it because I thought maybe it would help me, and I got killed.
The camera is way too close. It's hard to see things at times, and I really wanted to zoom back so I can assess the whole problem in front of me. Especially for later levels where you get more tables and have to stack them to reach the ledge--since I can't see the top of the ledge at all, it's very hard to tell if I'm doing it right until it's already too late, and I either got lucky and reach the top or I have to do everything all over again.
Speaking of which, reaching the ledge with 3 tables was near impossible! I tried to complete it for quite a long time before I gave up. I'm sure there's a clever solution, but nothing you've introduced in the game made that solution clear, and I freestyled tables for a while before I couldn't do it.
The ability to grab and drag tables would greatly help this game. And I assume (since this is something I relied on quite a few times throughout this game) that you wanted the player to turn tables on the side and hop on them--if that is the case, you need to introduce that in the game itself.
This is a bright game; it's quite astonishing that everything in it was made by you in a weekend. Bobby Tables leaves much to be desired, but I still had fun with it.
(P.S: Why is it Episode 2?)
