That intro had me sooo keen for the game to start - smashing work!
I was very confused when I got into the game though, not least because my inputs seemed to have no effect, and there was no animation or noise or anything.
I could see feedback when I was being hit, and creatures would eventually die, but I could only guess if I was having any effect on them at all.
I think you have amazing aesthetic, but would have loved to see the basics get more love and care.
Good job overall though! This was really cool!
