Ok, I tested the translation. At a quick glance, it looks good but I noticed that the word for "START" is spelled as "ΕΝΑΡΞΑ" but it should be "ΕΝΑΡΞΗ", the last letter of the Greek word looks identical to the Latin letter H. Also, I think the tutorial sign might be somewhat difficult to read with that bright strip of color at the bottom of the text, maybe you could make it thinner if that doesn't take away from the art style of the game. Other than that, I didn't notice any other issues. Thank you for taking the time to draw all these graphics!
