more cramped? I thought I put in at least one good dogfighting room in just about every level. Each level should have 'one' room where you got the space to do one good dogfight with the robots.
Level 23 (The Grand Hall) presents you with an interesting challenge right at the start (see the pic) with at least 4 fusion mini-boss, 4 red homer (Super Hulks), 4 or more Drillers, perhaps 6 "Defense Prototype" (fires laser 4), at least 4 red "Spider", and a number of Advanced Lifters ... all in one large room.
