I personally don't mind games with grinds like this but the rewards are few and far apart which I am not a big fan of. You do a lot of grinding and game gives you a new frame, rinse repeat. The MC is very unlikable. It's almost a cliche these days but to be fair this game is a bit on the older side, the first one came out in 2017 I believe? The spelling and grammar leaves a lot to be desired, makes you wonder why they never put any effort into fixing it. I do like the female characters to some degree, at least Rhonda. She doesn't have that generic female vibe that you see in most vn's.
Anyways those are my thoughts after playing the first one and the second version for a few hours. To me it's pretty mediocre in all aspects.
