Hey! Thanks so much for the feedback! I really appreciate you taking the time to download, check it out, and report back!
Replay fade out: Yeah, I noticed that too.
I'm using the Pro2DCamera plugin and I think I either gotta switch up the layers so the transition is over the UI, or wait a split second more to load the scene and have the icons completely shrink. For those buttons I think I used a Tween. Most of my UI is Tween, while everything in the environment is animator. Good catch!
The length of play was a tough one for me to nail down. With the nature of the game and upgrades, it seemed either the starting elephant was too short, and the upgraded elephant was perfect feeling. Or the starting elephant was perfect and the upgraded elephant could last for a very very long time. Or the starting elephant was great, the ending elephant was great, but the upgrades didn't feel very powerful. So... I'm sure there's still a lot I could do to balance the game to feel just right. Right now it's my hope that kids won't take the short length at first and feel bad, but be insentivized to upgrade their elephant and get better!
For Peanko, adding time with each Peanut is a really great idea! That could really give a nice exponential curve on people just starting out and people who have upgraded their elephant to the max!
For Outrun, I did mess with that idea of being able to lose a brother, but the gameplay seemed to last a little too long and lose excitement. It is an often requested feature though. So maybe I'll take another look at that!
Thanks again for all your feedback! It's really valuable to have!
