This is quite a short and sweet game! A nice story with a darker tone is always appreciated. So, no to drugs is probably the moral of the story. I got confused about what happened there. I guess the MC committed suicide? Can't really tell (it's probably because I can't tell what the thing shown in the end is). Though I am not complaining too much about open-ended stories. The graphic is great, audio is nice and fitting. The platforming part is a bit short, but for a game like this, it's perfectly fine. Inverted controls after taking magic mushrooms is quite a nice idea. I wish the whole game was about some wacky platforming though. Why not all-in on this drug reference :)
For a minor criticism, I'd say the walking sound effect seems a bit off timing-wise. It just feels weird hearing the sound without the character moving. The game is also a bit short, and I wish it lasted a bit longer. But other than that, I can't really point my finger at what's wrong with the game. Well done!
