Having beaten World 2, so far I can say this is a surprisingly amazing game. The gameplay is actually pretty nice, especially with powerups, and the item system is really cool. I'm unsure entirely if the throwers can crit, but I think it'd be an interesting mechanic if you could upgrade them so they can catch the spike on the way back, then toss it again with some tight timing.
Also, the rewards at the end of each world are phenomenal. The art isn't animated, but it absolutely doesn't even need to be with how the writing is for the scenes. It's better than half the VNs or whatever I find on this site in terms of quality and shit! Good luck with the future releases, I'll definitely look forward to them.
Beat World 3, all my points still stand. The little bits of dialogue between levels are also really cool!
