I love the theme and the way breeze through the game. It has dark souls-ish feel since you have to start over again (which people like - others don't). It's not my cup of tea because I don't like starting from scratch everytime - but I get it.
What made it worse for me was the... red "door thing" that killed on touch in the first level since I didn't know, what went wrong. So I tried again and had to start again.
The biggest issue though is the controls - you have to hit the arrow keys perfectly to shoot diagonally. That made me backtrack to a straight wall to shoot straight.
On the positive side: The music is wonderful and the credit song is a banger. The art is great, the game feels "well programmed" - no hiccups, no technical difficulties.
Great job, cool Theme, wonderful submission. You rock dude! ♥♥
