Do yourself a favor. Don't look up a walkthrough for this game. Enjoy it, figure it out on your own. I don't regret resisting the urge to look up solutions on a dime.
Half Minute Hero is a spectacular fast paced and simple game. It's very meta without being overbearing, provides a lot of options and possible solutions, and constantly pushes you to try new paths and continously improve on yourself. However, in making this port, there is one thing you need to know:
DO NOT USE THE NEO CARTOON MODE GRAPHICS FOR MISSION 26. THE GAME WILL CRASH.
This is a HUGE bug they missed, and one that they really should have caught. But they didn't. But, strangely enough, it's the only bug or blemish I could find. Just keep that in mind. The game is totally worth it, though. So please do yourself a favor and buy it. And enjoy the challenge!
