A straightforward platformer with a speedrun timer, we may have had a similar idea.
I thought the inclusion of the arrow showing where you are off the screen and the telegraphing of spikes and fire were a nice touch. In the fourth level, the way the camera is situated you weren't able to see the spiked platform off to the right so it was not possible to anticipate when it was activated. Near the end of the third level, not sure if intentional but because of the one way platform you can jump back to the top again. These were just little things, the game never keeps you stuck for too long, good effort on your first game jam!
