I'm on lvl 2, completed all quests disponible and now the only way to upgrade levels is on the CyberSpace, but I think it takes too much time. We spend a lot of Bandwidth per click and earn about 1-3 experience sometimes, not too often...
I need about 600 exp to upgrade, it will take a lot of time. Would be nice if you add more quests, it's very helpful, and if possible, a suggestion I let here is achievements, like: interact with X amount of Database, Server, Cloud... Use X energies, Use X Bandwidths... Always with a reward involved.
On higher levels the rewards are higher including exp. Also there are other ways to gain experience.
Some missions are just what you suggest - to interact with X objects. I could add more missions like that, yes.
