A great game! I love how it starts, how the main menu is a part of the game. It took me quite a while to figure out what you're supposed to do at the very beginning – I assumed I need to avoid the bugs and somehow get into the rooms, which were all locked. I really didn't want to go anywhere near the scary critters, as I imagined they'd attack and I didn't want them any closer to my screen…
The individual rooms were great; I really wondered what they'd be like once I got there (by the way, if the Update function in your game does nothing, it's wise to remove it completely :)).
Although I hoped there would be some more challenge and more interesting puzzles than 'walk to everything and press 'E'', which is probably the most important thing, but I understand you probably had some time constraints.
The background noises like the people talking in the design room were a nice touch.
The inventory slot/icon design is somewhat plain and uninteresting, though.
When pressing 'Start' in the end, I had some trouble in positioning myself properly in order to be able to select it, I think the raycasts (or whatever you use there) is a bit wonky.
The final music is the victory theme from Heroes 3 – sounds great, and matches the ending, but isn't it copyrighted? If so, you should probably replace it with something else to prevent the game from being taken down.
Anyway, for a jam game, it's definitely a very solid entry, and stands well as a meta-game on its own.
