Very cool gameplay. I finished all the levels, I can defiantly see this developed into a fully casual puzzle game. I would love to go back to play this game again with more levels.
Having to go back on forth to watch both characters and make sure the next move would not kill one of them is very cool.
I love how intuitive and simple the mechanic is but could include so many puzzle levels.
I actually had an initial idea of controlling all characters at the same time as that would create chaos, I am glad to see that this idea got implemented in a nice way.
Congrats on reaching 20 ratings :)
