Are you able to trigger cutscene at the window, or is that not happening? If you can get to the window you should be able to move up and around to push the TV stand down from above.
If the game isn't letting you do that, please let me know.
... Welp. That's embarrassing. Thank you for letting me know. The normal version just has a "The end" followed by the credits (which are also accessible from the settings menu) so you didn't miss any content.
Edit: Apparently the Steam version was even more borked. Thanks for pointing it out, I probably would have missed it otherwise.
If you're talking about the first level, movement is all you need, you don't get access to the full controls until you get past the tutorial in level 2. If you're having trouble past that, please let me know.
If you need a hint for the first level, you can push the TV stand down from above. I need to make that more clear, sorry.
Yeah, there's a fixed combo of three topics which will give 6 points (which is counted as winning). Order matters, and a correct topic in the wrong place gives 1 point while a correct topic in the right place gives 2.
The goal of the game is to guess it in the fewest turns.
Edit: oh, and topics can be used multiple times
