I really, really liked the design of the devil, her little climax animation is super charming and the machine's O face made me chuckle. It's totally the kind of character design that makes you want to draw fan art, which I think is a huge plus for the protag of any kind of erotic game ദ്ദി(ᵔᗜᵔ)
Even though it made my laptop fan go crazy I didn't experience any crash or any bugs, though as some have said before I did find the platforming a little slippery. I only struggled on a few double jumps so it wasn't too frustrating either, but honestly I think I would have been happy even just having the hacking mini game without any platforming on the side, it would have been interesting to see it be deepened a little besides different speeds. Some sound would have been good too, but on the other hand I was actually pleasantly surprised to get a little reward for getting to the end so that's a plus !
With your style and the personality in the animations displayed here I think there's great potential ٩( ˃▿˂ )۶
