I'm sorry to hear that.
I had to make some changes to the expression system, so I had to redraw all the eye shapes and mouth. At the time I thought that giving her lips would be an improvement. In anycase I'll try and make her more cute for the next one.
I wanted a move that uses her hands on the ground, but attacking enemies directly with her hands (e.x punching) didn't fit her very much. To me the cartwheel was the best option. If you have any suggestions for stationary attacks I'll consider.
As for the "flip-a-dip" issue, it's something I'm working to fix for the next demo since a few others encountered it as well.
Conney in 0.124 didn't have any abilities other than jumping making it bland a fairly bland platformer. So for the newer versions I started adding more to her moveset with the hopes of making platforming fun and enjoyable. I had to side-line bondage mechanics temporarily to do that. But I assure you I'll focus on bondage mechanics more and more as I make the levels.
As for the bondage Metroidvania idea. I do plan to use it in Conney, but as small escape segments of the game. There needs to be more variety in gameplay scenarios and the way bondage affects the game.
