Amazing :D! Very innovative :D! Loved it :)!
Some points:
- Controls can feel a little weird when pressing multiple keys (stuff like hold down right, then up - then release right -> direction won't change even if should).
- I didn't recognize arrow keys in the tutorial image at first. Maybe if left, down and right were on the same line, it wouldn't happen.
- Rotating by arrow keys feels a little too fast at times.
- Very cool narrative :D! But if I had sounds off, I would never hear the tutorial... Having visuals too might help.
- There should be an option to eazily quit (Esc).
I hope I see you in the first 100 ;)! Good luck with future projects :D! And with this one, if you continue with it :D!
