Visuals are super nice! I also like the fact, that you've optimized the game, by making it in a small resolution. Nice to see technically right approach. And ofc the music is awesome. Check out my game if you want. Made it in 320 x 180 too. It's a pity, that there's no HD rendering support in Gdevelop for small games, so everything that changes its angle becomes a mess. Anyway, nice game as i said!
