you could note everything you did in a personal notepad file if you are working on something big it will help you remember what you did and might help you in the future if you stumble upon problems (I do this when working on trainers or cheat tables or even playing games when I need to for example minecraft when I am in the nether) also you could add them in some sort of expansion pack we dont want unused weapons all the time and you could put them in very hard secrets that aren't easy to get and the ammo icon maybe? also I noticed you are invincible when you are controlling a rocket from the rocket launcher (alt fire) I hope that was intentional but kinda weird gives you time to think about what to do when you are low on health and could possibly help you kill enemies from a far faster which is kinda OP even when hiding in vents lmao
oh I do have notes .. i'm on notepad file 30 or so.. somewhere at line 12249 .. and they are not necessarily in sequence either - sometimes I just write things in the middle.. and I can't help it: I lost track of my notes long ago 😔
but that is just the thing - game design is always about making choices .. but there is never a good choice there is always a tradeoff:
e.g. you probably want to know if you get attacked while guiding the thing - but it's simpler to stay invincible -- but that is easier to exploit and makes things too easy -- in the end the simplest solution is to remove this feature outright - but then what to replace it that is useful and not boring? .. it's always a mess 😔
