Thank you very much for your comment :D
I really like the minimalist aesthetic, and I like it when the gameplay is obvious. I've included a tutorial just in case, but the idea is that I'd like the game to be able to do without it. So, I thought the simplest thing would be for a color code to say: Red hurts, Blue is vulnerable, Yellow activates, White is neutral.
Only for the winged heart was I unsure what to do. I didn't want to add an extra color, and using yellow didn't really satisfy me either, so that's why you can change your style in the game settings.
And it's also great fun to create graphics with such a color constraint.
Anyway, thanks again for playing and commenting ❤
