The game feels solid enough. The core gameplay loop primarily consists of grinding out stats to get sexual encounters to get exp to make grinding easier (by carrying over more of your previous run's stats, increasing starting physical stats, or buying more time for your next runs).
However, there are a few mechanical issues that I can see in this early release that prevents it from earning 5 stars. For one, the loop scales too quickly, losing your virginity in a run right now guarantees two extra days on your next one. As more content is added, that minimizes the difficulty for future runs (as you can effectively always scale to as much time as you'd ever need). A scaling cost system would address some of this by effectively slowing the player's progression as they get further in (which places more emphasis on time management).
InstaTok also currently feels like a shallow mechanic. It unlocks pretty quickly, but the information it grants (with one story-related exception) really only needs to be retrieved once since it is static. I wish it granted something mechanical when using the stalking feature besides a static stat breakdown.
