The game map is literally a board of circuit and the icon for the virus ships and abilities really fit the looking! Although there's a visual glitch that after the firewall was placed a slot and it went expired, putting another firewall again will not display at all, fortunately it still works. I also found out that you can just block the incoming virus ships with the firewall, so next turn they will remain "i" at the edge of a slot until the firewall is gone. But because the game will consider you win if there's no more virus ship in the board and the incoming reinforcement don't count, so I get a quick win by doing this. I think speedrunners will love this if they happen to find this game and record it to post on Youtube.
Btw, good entry!
