Cool to see the sex toys heroine in 3D! I like the model, she's got her own style and follows the proportions of the sprite. A small idle animation would really bring her to life. Maybe there can be some sort of room or segment with 3rd person view so you could see her from the front?
The view orientation gets weird at times, but it feels like part of the game, so I'm ok with it. Gameplay reminds me of Descent and the controls feel good, but it may be hard to judge how tight they need to be until some challenge is introduced. The only thing the controls may need is autofire if the player is intended to have infinite ammo.
Nice work on the prototype, hope you'll get a chance to expand it into something bigger!
