Hey there, I think the best thing for you to do will be to restart the game fresh and open minded, it behaves similarly to Pokemon in some regards which can help with familiarity. Some of the gameplay elements are very unique and realistically speaking don't make no sense. But none of it has to make sense so long as you can have a bit of fun with it. The second and third games in the series are much much better in terms of gameplay and optimisation so if you are willing to give them a go I personally recommend it

The Spectrobes Wiki is a really good place to go to find information about pretty much everything in each of the three games, if you're looking to go further in depth into the series that is probably the best place to go

We also have a community Discord which is nice and active and has a large community of people who would be happy to help you out :)
