I won’t rate because I can’t complete the game. However, I will review what I played:
Like you said, its mostly hard fighting. And yes, that couldn’t be more true. You spend the entire pack going around killing bad guys and walking around a level for 3 seconds before you come across a boss or get stuck. Eventually, you get bored JJNEXTing the levels you can’t do, so you decide to create a level with the horrible smudgy backround and stick a load of bosses in an arena, then my computer packs in.
