Nevermind Castle - tun tun tun... I do not know why, but this pipe makes me laugh)
Plains In My Dreams - Mission Impossible?) Heh... A beautiful composition with a curious bass...
Wild Doubts is Cute. Underwater. Cool!
Solace - Sounds... Sad? But it also seems to be fascinating.
Rejected Memory - This boss theme sounds very playful. Interesting!
Conflict Of Ideas - I like the way the track called "Conflict Of Ideas" feels like a competition between the drums and the basic instruments (Or I'm slowly starting to go crazy)
Deepest Thoughts - Oh, a time of mysterious and deeply ambient...
Wi-Fi Settings - whoa whoa (I love that router sound. Heh))
Overall, you've got a good chiptune. I'm sure it would be a good match for some old game ...
And I like your melody and the idea of the game)
Thanks!
