Wow! Thanks for the detailed feedback! :)
"In options menu: What is the difference between back and menu?"
The options menu is the same room whether you get there from the menu or from in a level. So if you get there from the menu, "back" and "menu" are indeed the same. "Back" takes you back to the level you were on if you were in one.
"I realy like it that you introduce the 2 characters at the begin."
Thanks! It's one of my favorite things about the game! xD
"I think the first boss is too hard"
For a solo player, yeah I agree, I would definitely advise using slow mode for solo play unless your up for a really hard game.
So far as I have seen, the first boss is hard but doable for two players.
"But once you solved the puzzels the replayability is not too great."
I was hoping that the ranking system at end would solve this a little, but unfortunately I think this is a built in problem with any puzzle based game. However, if you have some ideas, I'm interested! :)
Big thanks for all the detailed feedback mate, it definitely helps me out.
Send me a link to the game you wanted me to try!!! :)
I hope you had fun with Roopit and Boopit!
