I've checked the download link right now, and it's not broken. If your device is a tablet/console and is not using a mouse as an input, you might need to download the mobile version of the game.
Press and hold your mouse to aim and fire for desktop versions. If your gun is facing the direction of your mouse, the gunnery mechanism should work also.
Thanks for the bug reports! The lag spikes are due to the concentrated pixel-image suddenly loading due to the minigame. Was planning to change the high resolution scenes sooner or later, but since you mentioned that, maybe I'll redraw them while adding the other intercourse minigames (thus, removing most of the CG bugs mentioned). I'll also try to fix the other bugs you mentioned, but system limitations that need quite a long time to alter(such as the inventory) might stay a little longer since I tend to update my game once a week.
Also, thank you so much for the bug report! Since I update the game every week, code errors tend to occur and finding the errors are harder than fixing one. Let me know anytime, in any way when you encount an error and I'll update the game the following week.
You seem to play the unfixed(unreleased) version of the game, download the game in the dropbox again to get the version with the infinite mode fixed. And with the sex CG bug, I'll check the game again and fix the error this update (since the cg scenes for the rest of the enemies are to be added this week).
I just checked the game again, and there doesn't seem to be any errors in the code. I believe the recognition stopping issue might occur if the performance of the phone where the software is installed is insufficient. Since this game is developed as a cross-platform game, it might put extra load on mobile environments. In future versions, I will work on improving the performance for mobile players.
