Lots of fun, and really neat concept! The size of the queued marbles versus the actual marbles dropped made it a bit confusing figuring out aim etc early on, but I got the hang of it soon enough. I'm not sure putting a heart in the final bin seemed to do anything? Also, frankly, the second-to-last fight was much harder than the last fight, as those 3 snakes could really lay down a lotta marbles in rapid succession... That said the only thing that was mechanically odd was that the flat platforms had no interaction; no bounce, no redirection, no rolling physics, just pbbt they'll go straight down once the platform moves out of the way. A really great game overall though, and I look forward to adding a future iteration to my collection. :)
