The writing is pretty great (even though I spotted some grammatical errors here and there (I know you all are going for a poem-y sort of writing, but still, I felt like you were pushing the grammar a bit at some points)) and I really, really enjoyed the art direction. The game really captured that ancient greek look.
Programming and gameplay are a bit on the wonky end, though - the game doesn't seem that technically demanding to necessitate a loading screen. In fact, the whole experience could've been way better, in my opinion, if everything got a 10-20% speed increase. Like, I'd have enjoyed it more if the main character and Medusa both were a bit faster.
Finally, I feel obliged to bring this up: why did you enter this game for the "Certamente não é outra game jam" jam? I mean, clearly you've worked on this game for way longer than just one week... Am I missing something, or...?
In summary, I enjoyed the beginning of the game (with all the story, art and writing) but felt like the gameplay itself was slow.
