This game is amazing. I love how the bullets matched with the song. It was really well put together I thought. The controls are awesome and the visuals are amazing. I didn't realise at first but I love the way the health is displayed via the background numbers, such a cool idea. The only problem I had was when the song changed to the second part. I loved the shift and the dodge mechanic where you had to move on that grid was great, although I wasn't given enough time to understand what was happening before the bullets came at me, so it was a little punishing. Other than that, amazing game :)
The tutorial seems broken though.. But it's a game jam so that can't be helped.
