The death animation was so charming! I think it's great for a first entry and I think you should all definitely keep it up. It was a little hard to see the bullets, I don't know if the blue bullets/pallets really stood out at the speed they were going.
That being said, there were some really good details that I appreciated, such as the progress indicator through the level and the aforementioned death animation. Little things like that really make the game feel great.
