First of all, thanks for your feedback. We are happy to hear that you enjoyed our game as we enjoyed developing it. Even so, I have to tell that you are right in some way; we chose kind of an "easy theme" to develop around during this game jam. Do not get me wrong either, we are very proud of what have we done, astromadness its the best game that we ever have made. However, GMTK 2019 has been your fifth game jam as a team and we have learned that it is better to focus on a simple idea and try to squeeze all out of it than trying to cover a more complex experience and not finishing it. As we say in Spain, quien mucho abarca, poco aprieta, which means "trying to do everything, but ending up doing little".
I repeat, however, thanks for your clear feedback and we are glad that you had a great time playing astromadness. I hope you will enjoy our future launches too! :)
