Interesting game, but plagued by some serious balance problems. The Golem is in all situations the best pet outside of maybe and this is a big maybe, unlocking the Arcanist. Passive spellshard regeneration needs to be significantly better across the board. Anything that discourages auto-clickers should be good, and the idle mode helps with that, but the fact that you barely regenerate mana without clicking is problematic.
I understand you want autoclicks from pets and spells to be valuable, I'd have those generate much more shards than they currently do. As it is, the Summon spells are across the board too expensive to be competitive.
Good work generally, though.
