(programmer on the team)
Yeah, this was a school project made over 10 weeks.
If you're referring to the one mechanic in the trailer where you jump on a box to fly with it, we scrapped that due to time-constraints (hard to make work without bugs).
There is a big update planned for fixing a bunch of bugs, massively increasing performance and adding a few more visual effects, but that is currently all that has been planned.
I would definitely like to keep adding a few puzzles/mechanics to the game, but since I am the only team member still actively developing the game(in my free time) all of the work involved falls on me, and right now I don't believe I have the time to do these things. Maybe some time in the future, if I find the time :)
