It's really thematic, I found it interesting and I don't even like adventure games.
Two problems:
1. It's pretty unclear what does what. I know this is usual for adventure games, but I didn't even know you could combine items or switch clocks around until I watched the walkthrough.
2. The ending sucks. I know you're probably setting up for a sequel, but it still sucks. A lot. All the tension that you worked to build doesn't go anywhere at all.
These pretty much kill it as a game for me despite it's heavy atmospheric nature.
This is a pretty easy game. Fire/slow/fire/slow/fire stack in first rank, clean up with Digestion blocks on the last rank. Add some more fire/slow stacks, each one shorter than the last. With some minor variations, this clears out everything.
Popo's not glitchy, persay, just random. Also, not neccessarily a guy.
My theory is his gender has some sort of random chance involved in it from moment to moment.
Considering you need to play, on average, 100 games a card with a 50% win record to get a card, or 50 games if you're perfect, and the time each game takes... well, it's not very different from not having anything outside challenges.
The beta test version of Kongai was just plain better than this.
I don't know why they went this route, I can't imagine this is what Sirlin intended for the final version of his game. :(
