Excellent game. I remember playing the Riddle School series back in the day, and my friend and I would discuss on the context of Riddle School 4. We kept thinking that the game HAD to have some content, there was a whole map system and everything! Just look at the file size of the swf! The rest of the game must be hidden! But of course, there was no game and it was an April fool's prank.
Now your game is what I would have expected what Riddle School 4 would have been if it were a full game!
I enjoyed the funny scenarios, three whole floors to explore, and all of the cool references. Being sucked into another classroom in the middle of the game was unexpected, but very original. Great game overall, it really feels like a classic. The only feedback I'd give would be to keep the visited rooms highlighted on the map system, and iron out a few bugs (although it could have been Ruffle emulator acting up).
Awesome game!
