Alright, went through the entire demo and I gotta say I like the game.
My biggest gripe is that I saw no point in adding new strikers in my team thanks to the level up system in place. What I found myself doing more often is that I just did a few social events, and then grinded in the convenience store for money to get all the moves in game.
In my playthrough I also ran into a couple of bugs. Usually all the battles, while they say that you earned money the currency icon never goes up, so to compensate for that I had to work in convenience store often. And even then the store only pays half of what it actually promises you.
A game breaking bug also occurs with Seriza when you spend time with her. If you accept the offer for her to nurse you and unlock the sex scene. The Game's HUD dissapears entirely afterwards. While you can still open the menu via "ESC" you'll be softlocked in your room until you reload your last save.
Something that should also be remarked is that the player still technically has a reason to explore areas that the girls aren't around. When I observed certain areas at certain points of the day, I got an extra match, some money, and a free striker card as well. I sorta stumbled on that feature as an accident due to my curiosity, so it might be good to put in the tutorial that you can explore these vacant areas so long as there's a reason to.
But other than that, once you tinker with the game a little and understand the mechanics, you can have just as much fun as you did with Bengal's other works. Overall, I liked this demo, and eager to play the full version once it gets out.
