the artwork,physics and music are decent.Yet,the platformer is a little bit too confusing,and the clock worsens the problem.I also do not know clearly what part kills me.Maybe more indication could be added.
edit:I finished it.Took me 3 days,and it was an amazing journey.It feels so satisfying to beat the game and the difficulty gap may be the only issue.The retro artstyle and music are nice,while the gameplay is relatively smooth and without any bugs.Truly a gem!
