Wow! Thank you very much for your extended and thoughtful review, Aru!!! This has been our first BulletHellJam, and we were kind of exploring the genre.
We looked at our strengths as a team (2 great artists and 1 programmer) and decided to balance the experience on the art side.
For the next edition, with all this quality feedback we've been receiving, I'll ensure to do something a bit more interesting on the gameplay side!
Thanks again!
