Experiance

im trying to level up to level 1, and i have 2 questions about it

so I heard firstly that level 1 gives more bananas in the fun zone, about how many are gotten per watched ad? compared to level 0?

Also, im finding it hard to get experiance as i cant install games because i have no space on my computer, and i played all the browser games that I could find that give 100 exp
