Comments:

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.

I’ll start off by saying that I have purchased a few things, so I’m not just complaining about a free game. I paid for the 5x battle speed forever, I paid to always skip ads without watching them, and I paid for 3x mining speed. I have supported the developers. My main issue is with a bug, which hopefully isn’t intentional. When you complete a battle, it shows your rewards, which you can either collect or watch an ad for 1.5x rewards. It DOES NOT say that the 1.5x only applies to some rewards and not others. Specifically, it DOES NOT apply to experience shards or magic crystals, both of which you need a lot of. You get a good amount of experience shards generally, but magic crystals are more rare, so getting 1.5x would be great. This makes me wonder what other things the game says you might be getting that you don’t actually get. This should be patched immediately, because it is dishonest and misrepresenting what’s going on.

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.

Summary:

Given the slime status assigned to them by the Slime Sage, players set out to improve their skills, acquire legendary tools, and master great abilities to preserve their land. The fundamental duty of players is to protect the peace of the forest and win in spite of demanding obstacles. "Slime Castle – Idle TD" presents an exciting role-playing experience with seamless integration of tower defence game components. Together with the fundamental idle clicker features, the auto-battle system lets players engage in a fluid gameplay experience and start an interesting voyage. Along with discovering the secrets of the forest, players will come across a great range of maps and go throughout their journey around the game, each with a special set of powers. Your job is to thwart the plans of evil people over the several conflict phases of the game.
