Thanks for the feedback! It's meant to be a memory/puzzle game but I wasn't sure how big to make the levels. There was no time to test with real people because of the short time limit of the jam. Your feedback lets me know that maybe the levels are too big :) Also, the "coin" is a key that will open any door. If you open the wrong door you might get stuck in which case you can push R to restart the level. On the level you describe there's another door with another key and some health behind it that will let you kill the red demon. Thanks for playing and giving feedback. It's good information that I can use to improve the game once the jam is over. :)
