This was quite fun! I really like the pixel art aesthetics and the sound effects. The Phoenix character sprites and animations are especially great. The jump and dash abilities were smooth and felt great to use - though the ability to technically jump and dash indefinitely is a bit too free in my opinion.
My only real complaint was that shooting pushed you too far back. This cute little Phoenix recoils like a rocket launcher when shooting - which is honestly great to implement for something like a super attack, however I feel it's too much for a regular attack.
Overall: great stuff! The ending said "To be continued", are you planning to expand upon this in the future? If so, I look forward to seeing your progress on this.
