I believe I have tried it. Until the first boss, where I was forced to run around him and try to dismantle his armour piece by piece with a sling and stones. Of course he caught me while having the last piece of armour on. Uninstalled and never even considered giving it a second chance.
Fiddling with the script engine can lead to unexpected results.
I am a programmer myself and have an overall understanding of what can happen unintentionally. I don’t see how adding a few medkits in the inventory could lead to the boss to jump over the puddles :)
