The QTEs got pretty tough pretty fast. But, I thought this format was rather fun. If you do future games like this, a little slider to adjust the speed of QTEs could be beneficial. I added one to an old project that had a QTE after listening to some folks discuss their accessibility problems.
That said, the art was very nice. I like the characters and the varieties of body shapes. Seeing the slime's forms progress through out the game was fun. Overall, solid game, everything meshed well. The horniness provided a sprinkling of difficulty as I wanted to admire the art. (Another neat idea for post-jam update is the ability to admire the art.)
