It's a little scope creep for me. There is a lot of mechanics and only few levels to use them. The final boss was very well made (patterns were good and fun to learn) but unfortunately the bossfight itself wasn't very fun to play because most of my bullets weren't even able to reach it most of the time.
I like the art for sure! Characters in the visual novel parts where really pretty and main character during gameplay also looked very nice.
When it comes to movement.. the initial movement velocity and acceleration were too fast for my taste but most frustrating was when Neuro touched the wall and I couldn't make jump (before unlocking wall jump). The level design was brutal, everything is just too cramped.
This game lacks some basic juice in combat like hit feedback.
I like the soundtrack and the fact that different boss phases have slightly different music is great!
Overall the game is an a combination of well implemented movement mechanics and bad level design with the very well made bossfight at the end.
