Fun game, but I don't know what to do. It just seems like I'm aimlessly walking around levels.
The game is a bit labyrinthine, but your objective is to reach the boss who is always at the bottom right of the map.
Until you get there you can explore and gain skills that guarantee better performance in the fight, after beating it the map will change, and you will have the chance to find more enemies and improvements.
If you manage to defeat the boss four times, you will get the ending.
A tip, never stop killing enemies, you will be rewarded with up to four powers after beating a boss.
I hope you can have more fun now!
