Anime Marble Madness, intriguing. It looks quite polished already and the difficulty level suggests a high degree of confidence in the core mechanics.
That being said I couldn't help but notice some jank. It's been mentioned before but I also experienced the transparency bug in level 00, enemies can clip into the architecture a little bit in 03, sometimes the camera will rotate twice with a single press and the main character starts clipping out of her ball after respawning. Also, I have completely subjective mixed feelings about enemies.
The lives system is interesting but it's a little redundant if the player hasn't reached at least one checkpoint yet. Otherwise restarting is always a better option that guarantees a lower time and more total lives when a checkpoint is reached.
Keep up the good work.
