I’ve been playing this Jumping Flash! clone Forza Polpo and I like it. It can be pretty unforgiving–if you fall into the void it’s an immediate game over–but I think that’s okay because it adds a little tension when attempting a dangerous jump to get a few more of the (optional) collectibles. And the levels are fun and pretty short, so having to repeat one a few times isn’t really an issue.
It’s very much a 1990s-style “blue skies” game despite taking place on Earth after humanity has been wiped out. The music is good, too.
