not bad.
Not bad... I liked it. I sorta like... immediately beat it, so I'd suggest some like barrier that you can't pass until you do something to limit movement (think walls from older video games that you have to either get a key or do something to open the area .. or invisible walls that you do something completely unrelated to open them up is cool too.) Adding length and more objectives would greatly improve gameplay, but it's a good start.
Good luck!
