Thank you for your kind words and detailed feedback! We are evaluating what we will be doing with Lamplight Hollow next and will keep your feedback in mind to help guide us.
The problem with the 'Z' key not working is concerning and we have not been able to replicate it yet. As we look at porting the game to mobile devices we will likely add an on-screen button to replace use of the 'Z' key but it would be best if we could identify why this is not working properly for all players.
Thank you again for your thoughtful comments and for your time in sharing them with us!
