Wow thanks for this huge answer!
1) jea the haptics are something personal. My girlfriend dont lik it totally, for me its ok in this heaviness.
2) Thanks! Music and colors are one of the most important thing. Feeling sells, not features.
3) Interact with robochan? You have the items to guide him his way, you dont have to interact with hin? What do you mean by that?
4) We used a palette of 4 colors. My designer friend is strict with this and I love it. Jea I should have designed the levels more like "you start and see where the robochan have to go". Distraction is a great tool for immersive the player and stretch the playtime ;-) . In my other game I did this with the teleportareas to limit the player. Thanks for your feedback and suggestions.
Have a nice day!
