The game field mechanics are amazing. When I was little, I used to play pirates on a hexagon play field that I drew on a paper, and this is pretty much the same, only with space ships. The other aspects of the game could use a little tweaking, namely the upgrades.
Surprisingly good game, nice music and gameplay. Two notes: 1st- make laser auto-fire; 2nd - the difficulty curve becomes way too steep at some point, I just got overwhelmed out of the blue.
