The gameplay is a little jank, but not the worst I've experienced. It actually takes some getting used to. I even forgot how to dash until near the very end of the game. Another tip: You can eventually kick your powers diagonally upward.
The artstyle is serviceable. Some games' artstyles push me away from trying them, this one did not! The sex animations vary from eh to alright. Sex animations are just through specific contact and not through losing all hearts, iirc.
Bosses can be hard, the save feature is like an arcade machine unfortunately, it feels. At first getting a complete Game Over the two choices don't really matter, but as you progress further I think one of the options was start from the last checkpoint. The checkpoints are either at the beginning of an area or some random spot(?).
Most if not all bosses do not require the temporary invincibility mushroom. You can get 1 to 2 before each mini-boss(?)/boss (or at least I've always had that amount before each boss by not using them sometimes). Some bosses I could only tackle half-way before dying, whether it was skill issues or jank(?) bosses. There was at least one later boss I felt I could beat them without a mushroom, but I used it anyway.
The save feature seemed complicated with Game Overs, but I was able to beat the game in 1 sitting. There were more than enough tokens to continue, I think? At first I farmed a few at the very beginning, but was unsure if I kept that amount in a later playthrough (I feel like I restarted the first area a bunch of times before getting the hang of things). In the late-game I was around 60-90 tokens.
The story is not completely unique. But of what little I've played or completed of others, it seemed different enough. I liked it.
