Nice platformer, and awesome level design! Be careful with the music, there is some instruments out of tune in the Indiana Jones-ish song (unless that was a desired effect, of course!)
Combos felt really rewarding, and maybe it's a bug but I find it to be a feature: when downscaling the window and setting it horizontally (instead of full screen), you can see more of the level.
I wish I had the leash, as Indiana Jones has or like the Castlevania guy. Maybe you get it in a future level, right?
Nice submission, congratulations!
