I've used Pokemmo to get some new players into Pokemon, and I think those of us who have been playing the games for years don't realize just how hard the type matchups are to internalize, especially if you are playing only a little bit of the storyline maybe once a week. And not all of them are as clear as grass-fire-water.
I haven't had the chance to play through with a new player with the new UI changes, but I was happy to see them implemented in the last update and I think it is a step in the right direction. Personally I would like an option to turn it off as I prefer a cleaner UI, but it is no big deal. If you're a player who actually needs it to remember type matchups you're not going to winning any serious PvP games anyway.
However I think Pokemmo has two issues in its current state that makes it harder for a newer player to internalize type matchups compared to the games:
There needs to be a sound effect on hit for type effectiveness. The human brain is very good at remembering things through sound. The console games have very distinct sounds for super effective hits/not very effective hits, and this is an often overlooked means for teaching player's game mechanics, and its effects are really only noticed when it is absent.
Move animations. I know this is being worked on which is good to see, but it makes it connect that fire beats bug when you actually see an ember roast a bug as opposed to clicking a button and having it faint.
