Psychic Idle is an intriguing, sci-fi, fully-idle mobile RPG. While many such games seem ashamed of auto-control and try to reduce it somehow, this one states very clearly that you can continue the core journey without moving a finger.
Most of the time, you'll be watching a 2d pixelated show of a tiny character using explosions, lasers, fire, etc., to obliterate tens of enemies at once. The graphic here is pretty standard, with all the effects and smooth damage numbers - just enough to be pleasant. Enemies are also typical - some slimes, bandits, golems/robots, etc. - they won't live long anyway. The "decor" section is a nice touch here - an extensive collection of purchasable cosmetics - heads, garments, wings, etc., for your character. It ranges from new hairstyles or cool glasses to a giant bunny hat or fabulous nine-tail. Plus, a few high-quality large character arts are lovely.
The game plays by itself, but of course, there's more to it. Killed enemies will drop multiple resources - starting with ordinary gold coins. Other items could be only gained by making quick side trips to dungeons. They can be spent on various upgrades - as they're needed to face challenging enemies ahead. You'll be able to level up, research monsters, "enlighten" yourself, or even do a "quantum jump".
At the same time, a separate set of upgrade methods are based on "summoning" - a well-known gacha system. Unlike many other titles, you won't draw any additional heroes/pets here, but rather a piece of different equipment, drones, or even superpowers. Each of many summoning types got own counters, levels, and rewards, and each can be easily used in bulk/auto. That means lots of drawing - and fortunately, required premium currency is relatively abundant here. You'll get it for many quests, watching ads, and even some just by being offline!
Ads here aren't bothersome - but for optimal progress, you'll need to watch some regularly. This can be avoided by getting ad-removal from the shop - where you can also get packs, currencies, and cosmetics.
