This is a really faithful interpretation of the LSD Dream Emulator aesthetic and quite well-done! I did a playthrough of the game below:Some thoughts about the game -
You nail the strange vibe of semi-animated but fairly static elements that created uncanniness in LSD. I think the tsunami, the door opening in the mirror, and the cars were all great examples of harnessing this effect.
Your concept for the first mirror level was the best. I think it's great being able to play with players' expectations and use visual tricks to create that dreamlike sense of disorientation. I also like the implication that the shadows inside the mirror are just a formless void, without any light.
I hope you keep creating strange and uncanny little experiences like this. There's a lot of interest in them and they make for fun experiences.
