I chose the platformer game to analyze is 'Exit path'
The reason why I chose this game is easy to play but hard to master.
In this game, they are using only 5 keys for playing. Also, it has tutorial level! So, very easy to play.
This is the merged screenshot of stage 1 through 9. In stage 1 through 3, they explain the how to move and how to use special move. In stage 4 through 9, they shows which obstacles are in this game like saws, swinging axes, spikes and chasing laser beam.
While I played this game, I could feel the level going to be harder and trickier. however, If you have a sense of timing, you could clear the level easily.
This is the image I simplified to recognize which mechanics and obstacles are placed.
Here is the play video.
