For the folks having screen issues, you can modify the resolution the game uses by following the below steps. This definitely helped me because I have an ultrawide monitor and things were all sorts of messed up.
- Right-click the game.exe (恥知らず.exe) and select "Create shortcut"
- Right-click the shortcut created and in the "Target" line add whatever resolution you want (best would likely be normal ones like the list I noted below
- Example Target: I:\Shameless\恥知らず\恥知らず.exe -screen-width 2560 -screen-height 1440 -screen-fullscreen 1
- if you want to play in window mode, remove the "-screen-fullscreen 1"
- Click OK on the properties window
- Launch game and see if it fixes your issue
Resolutions (I only tested 1920x1080 and 2560x1440)
1920x1080
2560x1440
3200x1800
3840x2160
Hope this helps. If not... sorry, I tried.
Also, to be clear as to how much content there is, from the DLsite page for the game, the dev noted this, " There are a total of 7 animated scenes as rewards in the game.
If you find all 7 tickets, you will have completely cleared the game. "
