The game that exists isn't bad: there is an interesting premise with the buttons/switch/time travel concept, but unfortunately it seems to lack any resolution or ending.
The rooms that do exist are not implemented very well--they are sparse and lacking in interactivity.
A frustrating experience as it currently stands. I don't know that there is much value in playing this with so many issues. There may be an ending, but owing to frustration from failed attempts at interacting, I moved on.
