To be honest, when I played at first I got frustrated fast but after a couple of minutes I understood how to play it and I really enjoyed it so much. It is fun to play and gets challenging fast. The mechanics are well made and I like the graphics too.
If there is something I wish to change it is to give some time between losing lives so that if someone attacked me I lose like one heart every second or so because in some situations the one attack could result in losing 3 hearts successively.
Other than that, the game was very fun to play, the controls were not usual but I got used to them. Everything was well done :)
