The trick is that each power pill belongs to one of the ghosts. The fireworks effect when activated should reflect this in its colour but the effect ended up being rather subtle and the asset package's colours of pink/red/orange too close to each other to really make it out, so it's mainly the blue one where you can see it.

To some extent the "puzzle part" that the player should find this out on his own was intended, but given that there isn't enough of feedback for registering it made this bit of the game fail. In an update I'm planning I will add some markings to the counters to make it more clearly.

Also, when there are leftovers you couldn't deposit anymore you should at least stop collecting more of the pills...

Another thing that didn't make it into the submitted version is adding colour to the aggravated pills so there would be some indication that there is some connection to which ghost ghosted you and that you're collecting points fit this one's power pill.

I have already some ideas on how to fix the situation of them getting stuck together. It seems at some times they're aiming for the same position and fail to get close enough so the would choose another one...

Yeah, that I should increase the hit area for the pills had been mentioned a few times already... :)

Behold the mighty power of the NavMesh... :)

Sometimes they seem to block each other off from finding a new destination, so maybe I would have to give them some watchdog for that.

I had a Coroutine in for randomly re-deciding on the path, that didn't work so I threw it out (it was also a remnant of my initial attempt for a movement system). Maybe if I gave it another attempt to make it work and set its interval much lower than it was, it might just do what would be needed here...

I had tuned the player's collision range in order to keep out of walking through walls. When I added the pills it actually didn't occur to me that I could just increase their collision ranges since them being practically static they don't have any issues with the walls...

As for the lamps (as you call them), there is a connection between each ghost and one of them. The particle effect when they're fully loaded actually shows this, but the effect is really very subtle and the colours of 3 of the ghosts are a bit too close to each other to really notice. I didn't have time to do more about it, but I totally intend to make it more clear (OTOH it was very deliberate to have the hints on the title page more vague and not directly giving away how all is connected internally ;) ).

There are several ideas I've got about making it more clear. One easier fix is to frame the counters in the different ghosts' colours (and I need to address some placement issues about them anyway). Another thing I was thinking about is adding colours to the collected pills to make it easier to remember which ghost you hit last (or add some colour to the player's "ghost form", or both).

One thing I've realized through the feedback is that I should probably limit the amount of pills one can carry at a time. Perhaps even depending on how many would still be needed for the currently active target. OTOH the fact that some of them still remain in their "activated" state shows that you've overshoot in collecting... When I was thinking about what kind of info I should give on the charging states of the targets I had 3 options in mind (none, which was what I already had, but difficult for the player to guess what's going on; exact numbers which I did because it was very simple to implement; or "rough estimate" like a horizontal bar filling up or a "battery charge" style of indicator (for example having 4 small lights and for 10 pills one of them lights up) which I totally ditched because I was running out of time). I'm considering to add that "estimate" type and give all 3 versions as some "difficulty setting" option to the player...

(Size of the pills' colliders might be another thing to tune with difficulty settings...)

What do you mean about killing the game? I had some issues with the state handling between game running and pause, but I thought most of that was also related to being able to start the game prematurely before the opening music finished (which is one reason the buttons only get active with a delay. But the keypress events are probably independent of that and will already work...)

IIRC that was the cool thing about it that they didn't follow the player so it was a good escape route.

Blocking the path was the quick fix to throw out a mechanic I had no time to implement (and not a real grip on how to do it in the first place). I might get to it at a later time in an update...
