Thanks for believing in the game's potential!
It's important for me to understand exactly where the players get stuck, when trying to solve this puzzle. I'd be very grateful, if you spend a few minutes telling me the ideas and potential misconceptions that the game evokes.
Firstly "not quite knowing how to use the tools": Is it actually unclear how to use the tools? (Click on the tool, click on the grid above the tools.) I'll assume you meant that you don't know what the tools do, when you use them. That's perfectly fine. It's not an easy game and it might actually be too hard. Could you please tell me your best guess of what each of the tools is doing? That would help me distinguish the easy-to-use tools from the unintuitive ones.
Secondly "not understanding what the game wants for me to do to solve the level": What kinds of things did you do, when trying to solve the level? What would you guess could be the goal? Maybe my idea of how the game should work is less intuitive than yours. :)
It's great that you commented at all, but getting feedback that is a little more specific would be amazing. Thank you!
