Really like the 3D2D aesthetic, the levels worked well, there were no game breaking bugs, was able to access all the keys, although I would recommend putting a sign or some sort of color on the doors to indicate that they can be opened or not.
I liked the puzzle of finding the code, makes you feel smart at the end for remembering hahha
Enjoyed the concept of the secret lab, definitely see potential for this!
Would like to see more work on the music, for different sections, but overall is enjoyable.
