Hi!
A very nice game indeed. I had a lot of trouble though lol. Not a big fan of mouse and keyboard combined movements though(Hyper Light Drifter PTSD).
The obstacles are very annoying if you're not careful enough(which I am never), and I found the shooters to be very difficult to deal with.
One thing that annoyed me the most was that one rainboid can push another rainboid, so when I had lot's of them, I had some trouble getting a new one.
Otherwise, a pretty cool game and nice bgm!
