"You don't know better about more rare enemies, archievements, skins, pets, nest evolutions or special endings. So how can you know better?"
It's all in the map info screenshots. It's also mentioned in beginner welcoming screen at start of the game.
Hm. I guess it could also be added at the end of the game though.
I can understand that veterans don't like to play in Beginner mode and I don't blame them. If they want to leave the game, they're free to do so.
Convincing majority of Beginners in lobby to force them into high difficulty Pro mode is a different thing though.
We all don't like Beginner mode but it is needed and it needs to be played.
It allows me to tailor the game to new player's experience and increase the chances of growing our community.
Pandorium used to be in a tiring sinusoidal ping-pong loop of dying and reviving:
... -> veterans getting bored and leaving -> few Pro matches, mostly Beginner matches -> new people getting interested, community growing -> Pro matches played, little or no Beginner matches -> sooner or later veterans eventually getting bored and leaving -> ...
Right now Pandorium community seems healthier than ever but if veterans won't bother to play in Beginner mode once a while, it's gonna go back to that annoying loop.
So while we're at it let me say this:
I am very, very, very grateful to all players who take care of Pandorium community and spend their time playing in Beginner mode and patiently teaching new players.
Pandorium is not a solo game. Without those efforts we wouldn't be able to have as much fun playing it as we do now.
