I see that you've put some effort in creating these environments! I don't know how to explain it, they made me feel uneasy but relaxed at the same time. The music was really relaxing too.
The only thing that I had problems with were the bugs. The ones I found were:
- In the first scene, if you don't press "W" and keep moving forward instead, you'll eventually fall into an endless fall.
- After I collected the 3 special coins, the scientist stopped talking with me, and thus, I couldn't continue the game.
- Some collisions with the wood plataforms were a little off.
I also think it would be good to have some SE's for further immersion and a sprint button to navigate over known segments faster.
Overall, I really enjoyed your game, I just wish I could have seen its ending, because I got hooked to the story!
