I liked the dreamy and bizarre worlds and character used in the game and I enjoyed the first level of the game. The character design for the first level is quite interesting and a little scary as well. I did not find bugs in the game but I can tell you that I attempted the first level, the merry-go-round section, just through parkour so maybe you would like to adjust that because the player can just parkour to get to the location required.
The third world reminded me of my favourite cartoon, "Courage the Cowardly Dog". Will be looking forward to the completion of the game as I am very interested to find out what are the consequences of bringing the people from different worlds to the bunker.
Thank you for reading my comment and I wish you good luck in your future endeavours.
