I wasn't sure if the game was going to run well enough to play on this PC, but after struggling for a bit; I wised up and ran the game with only default system processes and it ran well in windowed mode.
Windows 7, Home Premium 64-bit; 6 GB RAM;
Pentium Dual-Core E5400 @ 2.70GHz; Intel G33/G31 Express (Chipset Display Adapter); Realtek High Definition Audio
Java Version 7 Update 55
It looked like task manager was showing that the CPU was the culprit. The game only used around 44% average CPU for the java process, but adding in system processes it somehow reached 74 to 90% when running smoothly.
Any higher and performance in the game begins to suffer as follows :
All sounds took a long time to load (up to 30 seconds) with each new song in this state. On the larger forest levels, the input cache also overloaded, resulting in glitch input : walking into things/swinging wildly at the air/parasite to the knee aka R.I.P.
But, as long as you keep CPU max around 90% there should be no issues.
Just thought you might be interested in system feedback.

With that out of the way!
The art was wonderful. Ever since I first saw the tutorial video on youtube, I've been anticipating this game; and the art surpassed expectations ;D A lot of variety, and some memorable scenes.
On the other hand the story, dialogue and characters didn't resonate deeply with me after the tutorial; well at least until towards the end. I suppose it was the mostly casual nature of the danger. I was more concerned with finding Zip, than of the strange parasite (evil ikachan-ish?) invasion that except for Chloe, didn't seem to be too concerned

(Risa on the other hand has been waiting for this glorious day, to show the world what she's made of xD)
But, I am curious to see where things lead. To see what has become of Zip... And I do admit they seem like a good group of friends. Given time I could warm up to their group...
Gameplay wise, I find the battles a bit frustrating. With the mostly random nature of their movements, I have to keep on guard to whack 'em as soon as they twitch into range. Slow and careful, or risk piling on damage and dying in a scenic park where kids are playing... urgh, the floaters!
But, the boss... now that was very sweet. Too awesome for a first boss. I was hoping for a slight change in behavior when his health was low, but <3
Oh on the subject of gameplay, my initial impression of turning was that the screen jolted a bit too quickly to the other side. But, I got used to it, and plus I started when the CPU was maxing out, resulting in an overly laggy experience. So, with that bias, I missed my chance to objectively make a good decision...
The music was good. It didn't stand out to me, but it fit very well. Reminded me of some indie games I've played at some point... Can't remember names...
And, SFX gets a thumbs up. Nice.
Summary :
The game just blends well. Art + Music = transitive floaty happiness, kinda like a dandelion
There might be a possibility for a darker twist to the story (RIP), but it could also be a thematic fable that many kids could enjoy.
Anyway, seems original; and I approve ;D
