Thanks for the kind words and review! If you don’t mind me asking, can you let me know about how long you played? I’m just curious as there is an intended difficulty climb but if it’s too steep of a climb then I probably do need to do some more tweaking.
The prices made sense to me from the perspective of completing the runs (each run should net you around 500 points if you escape and 1000 if you purify). In my experience, getting a defence item is usually quite easy when running away but a few other things that’ll help escape a chase are closing doors behind you to break LOS and crouch hopping.
In theory you should only need one successful run to get the key detectors and should be able to unlock purification after two runs and then the NSFW upgrade after two more. Over-simplifying it of course as I’ve played the game a lot.
Overall, the biggest issue with solo-dev (I didn’t have testers for this game) is tunnel-vision. Next time I make a game, I will definitely try and get people to play it before it goes public to make sure the difficulty isn’t too frustrating.
