Thank you so much for the review!
I've tested to background with another tones and the darker one was still the one that made the samurais more visible. About the mid color for the faces, you're right, but this will be resolved after the jam, since i'll continue to develop this one, but this time, with no color limitations :).
I'm so happy you've enjoyed the game! And also happy that you could figure it out what the game was all about and the feeling of playing it.
I agree with you that this game needs a Win Screen or something like that, took note for a future update.
You are right again, the sfxs could be better and we need some music, also noted for a future update.
Thanks so much for the compliments, I won't be updating the game for the this JAM anymore, since i've already started working on new content that won't be ready by the end of the JAM. So, the next steps will be working on a full game with new characters and some other features.
