I love the visuals. everything has so much personality.
The drill was hard to controls at times. When dashing into an object to drill, it felt like my entrance direction would be randomly tilted, when I was expecting it to be in the direction of the dash. I kind of wish it was a bit faster also.
Boss designs were awesome. I might be in love with the design of the second boss fight. Its so cool to me. everything about it. But I felt that the drill mechanic was being utilized less and less with each boss.
But yeah, good game.
