There aren't more than one strat. You either do as Viivii said or you lose which is my only complaint about the game but for the low low price that they ask for you can't really complain about it. Great game, I hope they make a second one with more variety and better balancing. I beat the game by upgrading cat and daily parts thing. Took me about 5 games to max it and once I started getting robots I beat it on first try but I haven't been able to beat it again since xD

My Strat was use most of my summons for base defense, have them all sit idle, with the minority of my summons out clearing out/exploring. I'd invest in the lightning ability the mosft first as once you get it to deal 1500+ damage, you can clear out any spawners your exploratory summons discover. At 5000+ you can invest most of your time clearing out all spawners found.

TLDR, Golem fighters stacked at base with knockback + other special parts such as triton trident, dragon head, watcher arm with control panel, etc.

While they fight off the hordes, you can have the speedster collect everything.

With my strategy, you're able to hold the game infinitely as there is no greater enemy beyond the space people. With draconid body for fire aura, harpy wings/phoenix wings for speed, golem legs/mechanical legs for more speed. With this creation, you're able to speedrun destroying enemy lairs as your units at base forever defends.

When you're under serious attack and your tower is low but you have resources, spawning your strongest troops while the game is paused allows them to do first hit during pause state. You can upgrade your lowest undead/tower upgrades to get the easiest hp for your tower for a low cost.

To get fast gold and complete the game the fastest, you can hold out with good range/spell troops at tower while enemies constantly arrive. The more forts you have discovered = the more gold.
Rinse and repeat til you're able to buy everything.

After doing that, you'd have a breeze finding all the recipes once you have maxed out all of your upgrades by doing the good ol' wave defense tactic.

One you upgrade your body parts to golem tier, it'll be a breeze for scouting out. Preferred to get this upgrade level as fast as possible alongside some other things that will help give you more mana as they are costly. (240 Mana)

Also tend to create units with the fastest speed to scout out resources and such. If you're able to, equip them with heavy damaging weaponry. If you're stuck with having your base easily being blown up by enemies and your troops are always somewhere else, tend to create ranged units who're capable of knockback. (Tentacle arm, King's head, Cyclops boulder, etc)

v yep

This latest patch has changed how the game works now, the cat will now start enemies spawning from camps
