I've played the demo for the game, so my review might not cover all content. Anyway, from what I did experience, I've got some mixed feelings.
First of all, the game looks very nice graphic-wise. I like the design of the characters and enemies. The combat system was fun too, as were the animations in general.
However, the game was a bit confusing. The main thing being, I had no clue where to go. The amount of stars needed, how many were left..
I was not able to finish the demo though. I'm horrible at platformers, so did not make it through the second level.
That all being said, I've made a little video on my playthrough. Hope you enjoy it!
