That’s pretty cool. Easy to use. An ability to add sounds would be cool but not necessary.
One issue I had, when I created Scene 0 which linked to Scene 1 and 2. From Scenes 1 & 2 I tried to go back to Scene 0 but nothing would happen. Going from Scene 1 to 2 and 2 to 1 worked fine.
Overall, I could see myself create a game with this.
The smiley was a nice touch.
