Yes the early game grind is something several players have criticized. It's definitely something I'm going to look into improving. If it helps, remember that the grade simply determines how much your stats go up each time you attend that class. Currently the most you need in any stat to complete all quests is 30. You also don't need gym stat for anything currently. I may also update the item descriptions of the giftable items to better hint at which character they should be gifted to.
The money that lays around is collectible each day, not just once a week. There are three spots in downtown and three spots in the suburbs where money can be collected. The spots they appear are actually supposed to be randomized every time but due to an oversight on my end, they're only randomized...some of the time. I'll have to fix this. In future updates the player will be able to make money through more legitimate means like jobs or completing tasks for people.
Thank you for your kind words. The game's development is a time-consuming and sometimes stressful task but it's the responses from players like yourself that motivate me to continue putting in the time and effort to see through my vision of making this one of the best NSFW games out there! 😄
