I did not like this game at all. Here are some issues I had with it.
1. The Controls: Why would you make right mouse jump? The space key is normally the jump button and if you needed a dash key then you could have used shift.
2. The Graphics: They looked sort of mixed up and didn't feel like the went together. The ground looked liked it was made using a stamp tool in some places.
3. The Feel: Everything felt off even if it's jump to another platform or attacking a enemy it felt all kinds of wack.
That was some of my issues. I'm sure I have some more but I don't really want to get to deep into it.
Also one minor question: Is the lore explained in the game anywhere? I would have never figured out that the cape is demonic if I never read the description of this page.
