This is a very cool concept with very good execution. The artstyle is fantastic and fits the game perfectly! I think with a little more time this game can truly shine.
Some notes: The main menu seems very busy, which isn't always bad, but at least personally when it comes to large amounts of information it's nicer if it is sectioned off in some way. Another thing I'd like to mention is the readability of all of that text. White on green is quite hard to read, especially with some background lines being close to white. Adding a simple border to the text would help massively!
Regarding gameplay notes, there's not much to say, other than that it seems that it's relatively easy to trick the red player! Perhaps adding a difficulty curve or just randomising where the Red will go/start from to make it a bit harder to just repeat the same move over and over again.
Other than that, very well done! Execution is lovely and the use of sound is spot on :)
