I figured my notes from reviewing the games might come in handy, so here's what I wrote about your game as I was playing:

Very nice platforming feel, really missing some sound effects here, anything would be better than silence. Feels like a coherent thing, the art brings it nicely together.

The theme was very clear and fitting for this jam. It's easy to understand the message the game is trying to convey. I liked how you managed to include the message on the travelling commercial inside the game itself and not only have it as a post game sentence.

Controls very clear and introduced nicely with the in- game tutorial boards. I knew that the game was about collecting lightbulbs/ideas already before playing but I'm almost certain that it is very easy to pick that up from the travel commercial because it tied together the image of the lightbulb to the idea of new experience. Also lightbulbs are usually anyway mentally connected to having an idea because of the cartoons.

Only unfortunate thing was that the game was really short. I would have enjoyed playing also a bit longer levels and the levels could also have some obstacles/difficulties which might have made the game more fun to play. If you were to continue the project one idea that you could consider (and might already have?) is that the different levels might have different graphics to even better show the differences between the four countries.

Good interpretation and execution of the theme! 

If you have a chance to try either of the games I participated creating (DNA & Travelling Neighbors), please consider leaving at least some feedback for it. Positive or constructive are both welcome and greatly appreciated.
