for me it get so buggy at my first play too everything was buggy when i click or when anything happen. but it was fixed for me and the game just work perfectly fine as if there was no bug in the first place, what i do was change my resolution to 1980x1080 set to fullscreen and graphic to highest and then when i enter the stage i immediately go to map and choose enemyhouse after that i test a few animation in there and see that all of animation working just fine, clicking with mouse back then resulting in bug where the game just stop while i cant do anything now it work just fine, item work just fine, save has just one slot for now but work just fine, there are 2 set of clothes in the mc inventory, there are some sex scene if you not clear some area npc in that area will be captured and you could see how she get gangbanged too. the rest is just to go back to alley and play the game normally and enjoy it. (I think it was because i set to fullscreen while before it was windowed low and low res too that fix this idk)
But after the first boss in alley your sis will bring you home where you could modify your character hair, it hair colour and other customization in the game. This is as far as i play now but no bug to be seen from here and im still trying to find a way to unlock extra, but really i like this game personally it just bring nostalgia of old porn flash game but with smooth and better animation, play a old version on this thread and i could sure see improvement both in animation and graphic quality, there are new animation to play too (zombie had more multiple animation like missionary, felatio, paizuri,etc there are sex with dog animation and there are animation with giant boss zombie too). deffinitely going to wait and hope for more animation with more variant of enemies.
