We did note the control issue people keep pointing out. We will see how we can improve these in later stages even though we believe its more a "getting used too" thing for most.
For the theme, we planned a lot of spooky/horror elements, but because we usually prefer to be as bug-free as possible we focused a lot of time on perfecting core systems, which also affected the hint and any other text implementation. We plan to make better use and implementations of these in future patches of any other games.
Overall, we thank you for your feedback and for playing our game :)
