Is it just me, or are this guy's games really poorly designed? The artwork is legitimately second to none (too bad it's censored tho), but the games' mechanics are just bad. In this one it's slightly less annoying than the Rock Paper Scissor stuff from the previous ones, but it still seems like the game is made to be actively annoying between each CG. Like what was even the point of making Bulma walk through the section with hidden holes besides padding the runtime?
I'd love it if Yamamoto collaborated with a team with experience making RPG Maker/Wolf RPG games (like Acerola, or Happy Life, ...) and let them handle the game design while he just focuses on delivering artwork.
