This was definitely very intriguing and innovative.
The biggest problems I found were on the readability of the things I was able to do on each sub-game, especially on the 2d platformer one. I recognise the same world in the terminal, rpg & 3d but the 2d platformer is way too abstract. I couldn’t figure out how to pick up the key after breaking the vase so I had to look in the guide you made.
The game became more and more engaging the more I figured out how to navigate through the different games to perform all the actions I needed but I never really understood the sidescroller part of the game and every time I had to pick up a key felt like a big chore to me. It would be better if it weren’t so abstract and the layout mapped with the actual layout of the house. Also, it would have been cool to have a narrative explanation on why you can only perform different actions in different games, because it feels weird not being able to pick up a key when you can interact with things. I think that a small explanation would help the player understand a bit better the world they are and how to play.
I also feel that the terminal part can become a block for people that aren’t programmers or haven’t played any text-based games. Maybe adding the available room names or objects that you can interact with text would make it a bit friendlier and easy to use for everyone.
All this said though, great job. It’s very innovative and refreshing to play something like this. It forced me to break all preconceptions I had of how interactions work on a game to be able to advance and that’s a very clever puzzle to make. Thank you so much for the game, I enjoyed it!
