Man, Double Bomb isn't that great until stats get maxed...I've been playing a first New Game+ recently and Uzzi Punch is doing way more (2x or 3x easily) damage (w/Crisis Arm though, so I have to constantly make sure Robo's stupid ass is healed properly)...
Oh, and Grand Dream relies on Frog's Frog Squash tech, but all the other techs it uses are healing...>_> So is there a difference in using it rather than Frog Squash itself???
