Pros:
The artstyle is beautiful, especially the "overworld" bits. The levels are often very short and you are killed in one hit. This makes it so that you repeat the same bit over and over until you know exactly what to do, and can then execute your plan to perfection. This makes the gameplay feel very satisfying and rewarding.

Also, the abomination designs are gorgeous, and super terrifying.

Cons:
Most cons with this game are mostly small annoyances. First off are the controls. When scrolling the menus using the controller it scrolls way to fast, and sometimes it skips options. 

My second complaint is some of the level designs. Some objects feels kind of awkwardly placed, like the abominations that are sometimes placed too close to the obstacles. In my opinion there should have been some space between the last obstacle and the abomination so that the player can have some breathing time.

My last and biggest complain is the game's performace issues. I made it to the 6th level in the moon base (which I presume is the last one), but I can't finish it because the more I play the more the game slows down. I think it may be because of quantity of the projectiles but I'm not sure.

Overall: I super-enjoyed it, but I would have liked to be able to finish it. With some more polish the game would be a 5-star perfection :)
