Hello Malerouille, I've played and enjoyed each of your games, and this is hands down my favorite.
You always have such creative concepts, innovating new forms of gameplay and the erotic. This one integrates those really well and has a massive amount of potential.
I know the games you work on are often limited in scope, but I really hope this one gets many levels and potentially even a level creator.
In my opinion nothing needs to be added or changed about the core gameplay for this to be a complete game, this game could simply be expanded with more permutations to play as.
There's a lot of room for depth of play here, and opening up level design to the community could ensure that gets fully explored.
It genuinely gives me the same sort of enthusiasm as Creeper World 1, in that it's a creative take on tower defense that can do a lot with a minimal set of mechanics.
Wish you the best.
