Slime Castle: Idle TD RTS Game 12+

Fun game, but a couple flaws

I got this game a couple months ago, and I’ve been enjoying it ever since. I am currently on chapter 6 wave 29. I see what people say about the paywall, but this game is worth the time to get over it. Some of the rebalancing changes in the new update made the game much better. However, it has one issue: Ads. While it doesn’t force ads on you(thank god), they have broken their way into almost every aspect of the game. want X2 mining speed? Ad. Want to open the artifact chest? Ad. The slime shop partially counterbalances this issue, making the game more fun. Because of this, I feel the slime shop(currently lvl 2) should be available in tower of the wise lvl 1, and tower of elements(currently lvl 1) should be moved to tower of the wise lvl 2.

Scammy mechanics

This game’s mechanics are incredibly frustrating and feel designed to push players into spending money. I’m stuck in a battle on hard mode, level 10, against an enemy with life regeneration. My character has enough regeneration and shielding to avoid being killed, but not enough damage to win. We’re locked in a stalemate, which feels like a deliberate design flaw to create paywalls and grindy mechanics.

I spend 12 hours a day farming, using a second phone to run the game at my highest difficulty. Despite weeks of effort, I’m still stuck on level 4 in normal mode and level 1 in hard mode. I’ve purchased bonuses, reset my stats twice to optimize my build, and carefully balanced damage, survival, and crowd control stats. I’ve maxed out resistances, dodge, crit chance, mushrooms for area damage, splash, and multi-shot abilities—yet I’m still not progressing. Even after earning 125,000 gold in about 40-60 minutes, several times a day, the grind is unbearable.

At this point, the game feels less like a game and more like waiting for a chance to actually play. The pace is excruciatingly slow, even after removing ads, and it’s clear that spending money is the only way to make any real progress. Sadly, what could be a fun experience is ruined by the pay-to-play mechanics, turning it into a frustrating, tedious slog. Not recommended!

Since the game is developing and changing, we are sometimes forced to introduce changes to in-game purchases as well. Ingame purchases only accelerate your progress. Thank you for understanding!

bad UI, lack of content, need to rebalance progression

This game is cute for the first couple of days. However the UI in game is really clunky and janky to navigate across different pages, I have spent on the game to help with making gameplay tolerable (removed ads and x5 speed). despite this the progression in the slime village is far too slow as the drop rate for stones to upgrade is insufferably low (1-3 per level if you're lucky, sometimes none at all). with the x5 speed multiplier grinding one chapter for 1-3 stones is at least 10 minutes. for context you need upwards of 100 to upgrade ONE of several buildings. even after this you will still hit a wall as any slime not bought with $20 will not let you successfully pass chapter 9 unless you basically max out every skill which could take months of heavy play depending on gear RNG (which is also comically low). outside of actively grinding the afk rewards are limited to 8 hours and this amount does not allow for meaningful progression. The most successful way to enjoy this game is to go afk permanently
