Very nice game! 2 things I had in mind. I didn't understand you had to jump on top of the enemy ships to destroy it. I had to find it out accidentally. Second thing - I think it would be very good if you could implement a jump streak mechanic or something like that where the player gets more points if we jump from enemy ship to enemy ship. Other than those, very good music very good sfx. Liked the simple gameplay. Well done!
