Thank you for the comment! I actually made it reeeeeeeeeally quickly to be on time for the jam, just basing on an idea I had in my head. I totally would like to dev it, maybe in the next months, and I imagine it on a bookmark for sure.
Originally, there was a pre-made drawing for the bookmark and the alien that should be used, and it helped to point the objects to explore, but it was not efficient and I removed that part. I also had the idea to base all the game on books (so you point at words and phrases and not to real objects) but I didn't like it so much.
Let's see, I do not consider it finished for now :)
