Nice game concept. I don't think I never played such game.
Since you are using Lazarus and LCL from what it looks like I'm guessing you could make Windows version of the same game with minimal changes. If you don't have Windows computer you can easily check and debug most Windows programs in Wine environment.
I have also edited your post to link to the external image from your web page in order to preserve the GIF animation.
You can do so in the future yourself. How? When choosing to Insert image, you choose "Add from URL" and uncheck "Retrieve remote file and reference locally".
If you add your image from computer or keep the "Retrieve remote file and reference locally" checked the image is always downsized and converted into JPEG. This is done in order reduce the storage usage on the server that PGD site is hosted from. Without this we could easily ran out of storage space.
