This is a great game! Only observation is that a bit more room at the bottom of the screen would've been nice as I had little space to move the cursor in.
I also bugged the audio by dying in space, so I did not get to listen to that space theme that seemed epic.
Other than that it was great! Nice job!
Thank you ! Space on screen has been a problem during development, as I wanted the player to the see far above him, while he also needed to see the lava below. A thing I could have tried is moving a bit the camera depending on where you aim, which would probably help, mostly when using the mouse indeed.
About the music bug, I realized it too late, and got a little frustrated that I had no time to fix it, but it will be done :D
