So yesterday I was super tired and when playing the game I really did not like what was going on, especially the long delay when starting the game (the progress bar freezes for about 15 seconds).
I did not rate the game then because I though it might be unfair to give you a bad rating because I was tiered and so I just tried it again and it was much more fun. The ghost model and the player cape are really well done and you have a couple of nice shader/particle effects. Visually exceptional.
The gameplay itself is a little simple (and I still don't understand how my ghosts friend fight) but due to the progression of the enemies still entertaining. The player progression system is a nice idea and depending on the playtime could get interesting but for the time I played it didn't really became relevant.
