I think you had an interesting idea here and I'd love to see what you made with this idea, but unfortunately I can't even finish the first mission because the collision of the highest platforms with the eggs is not working, I keep falling through the ground on the second floor, I can't interact with these eggs up there. That's kinda sad cause you say your game is 10-15 min long and has 4 endings, I can't see a single ending :(
The music is kinda cool and fitting, but the style also fried my eyes like crazy. Especially with the background on your project page. It's interesting to see what kind of effect these lines have on your eyes if you play with the project page background visible for a couple of minutes but also really exhausting for the eyes lol
Edit: After replaying and having a closer look at the description I kinda got it, I managed to get the eggs from the platforms to mother multiple times. Really cool idea with the isometric perspective thing, but I have still no clue how that room is actually setup in a 3D space, would be very interesting to see the editor version of the room :D I tried many things but I think I got only 2 different endings. Oh and the eggs kinda broke randomly at some points which was kinda annoying when I tried to get 4 eggs to mother.
I think overall this can be a pretty cool concept, especially if you improve the visuals and build other types of illusions and more rooms. Maybe even have some rooms where you have an additional perspective to look from to solve the puzzle. Definitely a pretty creative idea of a game!
