Hi, ro-ses!
Thanks for joining the fun, Guntur is flattered and your question is noted! x'D
Hmm... for itch.io's game version, I'm afraid you'll have to remember it by yourself ><;
But! I'm planning to make achievements for the Steam version so you should be able to track them -^.^)/ it'll be quite some time for me to make the Steam version though. I have to finish making rewards for my indiegogo supporters first; such as the bonus wallpaper, artbook, etc...
I hope I answered your question! Stay tuned and don't hesitate to write another comment if you have more questions >u<)/
xoxo,
SweetChiel
