Fun game! I feel like every time I've played a TRON style game the path disappears behind you, but the persistent paths in this game really created a new dynamic for me of controlling space (securing enough space for yourself and leaving as little space for opponents as possible)
I only got to stage 6 after a few attempts but it was really fun! I would have liked a way to save your progress in some way (possibly every 5 levels or so), but I realize you're likely going for a more arcade-vibe.
Anyway, awesome game and thanks for sharing!
