Nice, short, challenging game! I think the graphics and sound are very well done, especially for a one-week time frame. The level was designed very well, quite challenging, but the check points were spread out enough that I didn't lose motivation pushing forward. The way the double jump works took a bit to get used to, but once I did, it was very satisfying and I felt in control.
Very good entry!
Well, thank you, too, for creating it :)
