The Undead "Night Time" spell claims to boost the production of assistants for 20 seconds. This boost does not affect faction coins, however, which assistants help procure. I suggest changing the wording of the spell, or adding faction coins to the boost.
Glitch I've encountered while trying to beat level 200. The dragon one-hits me, and so I go back to farm gold on a lower level for a few hours. Bump up the Warrior's health and then just hit the Auto Forward button to get back up to the dragon. BUT... it shoots me up to level 201, bypassing the dragon completely. So now I'm auto-progressing from level 201, and didn't have to beat the dragon. WUT?
For me, getting past the first dragon at level 100 required the following: Warrior health level 111 (600 health) to take the first hit, Rogue stun level 100 and speed level 100. That way, after absorbing the damage from the first hit of the dragon, the Rogue left him standing there stunned, unable to hit at all while my Warrior plugged away at his health.
One tip that's not obvious from the main screen (it's a scrolling tip) is that if you 3-star a world on monster difficulty 7 or higher, it'll automatically level you up. So once you've progressed part way through the map, you can go back and do the first couple levels on difficulty 7 to level up faster.
From what crafting I've done so far, the demonic equipment seems to give about 5× the base stat of the magical item it is transmuted from. Keep that in mind if you're too eager to use some coal immediately. When selling, the legendary has given me an average of 2 million, and the one demonic item I sold gave me 10 million. Not sure if that will ramp up as stats increase.
TIP: when you finally do get coal, your first demonic crafting should be with gloves + feather. The gloves stat increases luck, and demonic gloves will greatly increase the quality of all future drops, including coal frequency.
How I got the 144th star: use the last ship with four weapon slots, arm yourself with the Meteor Canon (sic) in all of them (fully upgraded), and put Damage Amplifiers in all four of the ship's addon slots. Success in getting all 128 kills on the level seems to depend on the placement of powerup drops. Sometimes a ship will get through, or you'll die trying to prevent it. But powerups or bombs at the right time should see you through.
LEVEL 9: I used Foodini to rescue Papa, but mostly because helium-filled balloon whips are cool. FIRST ROOM: you just have to jump on Radley's head once, hit him, and he falls off the edge. Then, race UP the level ahead of the rising floor of spikes. This'll just take practice. SECOND ROOM: Radley shoots his Foodzooka at you while radish paratroopers descend from the skies. Kill them as they descend, and hit the projectiles fired at you. ONLY THE YELLOW ONES will rebound back to Radley and knock him down -- then you jump on his head and hit him. After you do this twice, 2 Burgerzillas join the fray and Radley starts to shoot faster. He's defeated after the 3rd knockdown. THIRD ROOM: free Papa!
Found a bit of a glitch: on level 4, the little moneybags guy who can crawl is able to crawl past the top of the boulder blocking the small room with 9 (or so) coins, but he can't get back out. Gotta quit the level.
Far better fare than the regular churn of Papa's [insert food]-eria. No doubt this will get badged in the near future, and probably forgotten shortly after. Still... I gave it 4 stars for the effort put in. I just wish Flip would be willing to attempt something like Remnants of Skystone again. After seeing what this game studio is capable of developing, it's consistently disappointing seeing relatively pablum productions of cookie-cutter games. It's like seeing Quentin Tarantino write and direct an Adam Sandler movie. You're capable of SO MUCH MORE!
