Now THAT was fun! I Love the multiple endings. The multiple-key rooms were good too. The platforming element is perfect and I can't suggest any improvements there. I was a little disappointed that the birthing wasn't ore of a feature for many of the puzzles, but I can't ask for too much since this was very well made overall!
I wish I had the mindset to make puzzles like this, but I guess I'm better at solving them than making them. If you ever want to collaborate on something, message me at zedslabs.com. I would be proud to be involved in something like this. I think there is a lot of room for growth (hurr) in terms of sequels or other such games.
