Thanks for pointing out specifically the reasons NeuroBurst!
Our goal to the game in the Global Game Jam was to make a "hard game where someone must fint the correct object in a sea of lost ones" and that's why point 2 is so hard.
Point 1 is something that we dabbled on and tried different timmings. At the moment for each 10 seconds an Alien spawns.
Point 3 is a kinda of a neutral one, since it can help the player to clean the room but also consume the items the player needs! Keep them out of the way :P
I often keep some items in the other side of the room where the roomba can't reach :D
Regarding the co-op, once you activate it, when you press PLAY you can play with someone else!
I'll keep posting updates as we keep developing the game. Thank you for your feedback!
You're welcome!
Also, something regarding the download; I noticed you have a seperate .pck file from the executable, which is kinda annoying do download separately, so what you could do is put the .pck and .exe file in a zipped file, so you can download it once!
Also, I'm just wondering, but are you still going to use godot for your future games? I also use it and It is very good!
