Tangent Gatlin: the Euler Settlement by Bx007 (itch.io)

Still in development, and in this update we have:

1. BGM included (non-original)

2. bugs about fullscreen button fixed

3. adjust some parameters, now the hero can jump higher, but the recoil of the gun becomes smaller to make it more difficulty to just fly into the sky with the gun! ( and this also make it more difficulty to find the easter egg)
