Thank you for playing and for your kind words!
On keyboard you can just press the shoot button, Z, to start the game.
Unfortunately I can't help you much with Linux-related issues because the game hasn't been tested on linux, and the Shmup Creator engine only supports Windows currently. I'll ask the engine dev about it though

It crashed again. This is the last line of the Ogre.log file (the other lines are unrelated and from minutes earlier):
23:08:47: Ogre::RenderingAPIException::RenderingAPIException: Unable to set light details in D3D9RenderSystem::setD3D9Light at C:\OgreSDK\Ogre3D\ogre\RenderSystems\Direct3D9\src\OgreD3D9RenderSystem.cpp (line 247)
It's apparently a problem with Direct3D, so it's just a Linux / Wine problem and not a problem with your game.
I'll investigate the issue later. I added the game to a private collection because now I'm curious about the lore and all that cool stuff.
