Too good to skip

The game is free-to-play and doesn't force to pay to collect characters that you like with a generous premium currency income unless you are extremely lucky or a min-maxing person. The majoirty of characters are viable and quite unique, even some with lowest stars. The art and music are peerless. You will stare at illustrations more often than playing ( ͡° ͜ʖ ͡°) The gameplay is neutral. Some love it, some not. Either way, connecting 15+ tiles and then making bosses evaporate is addictive. The endgame -Spire- is challenging and really depends on the players' strategy (so you don't slap bosses with money) Kind of grindy as first (like most gacha games) but become better later. The energy refill price is reasonable. There are free energy packs here and there so you can pace yourself without worrying about losing efficiency if you decide to become lazy to play one day. Developers are responsive and do listen to feedbacks (BIG ULTRA PLUS pros of the game). My only minir complain is that the RNG element of grids is really bothersome. There would be a big improvement of quality of life if there is a shortcut to restart stages because players are going to reset stages with bad initial grids anyway. Characters with reset tiles like Uriel is still good even with this because the reseting skill is faster than loading a new stage and they have a better chance of generating desired tiles.

A must try !

This’s easily one of the best gaming experiences I’ve had in a long time; nothing feels redundant, perfectly designed auto functions, well done character design -as well as character specific dialogue (just the right amount of it) and the game is deep with strategy. Hats off to you devs for creating something that captures as many popular interests while doing something completely unique, 10/10. My only criticism as of now are the account backup options, as there is no way to link an E-Mail, just social media or, in my case, Apple account.

(Edit).. everything has been great since my former review, just wanted to add that I really wish they would remove all the harassment surrounding players sleep schedule. Beyond a certain amount of gameplay you will literally get bombarded with messages about needing to sleep/go to bed via txt messages, base interactions/Gen dialogue. Then again if you log in earlier the next day about “being an early riser” & get harassed again for being “too hard of a worker.” Some is fine but this is REALLY beyond obnoxious, offensive and tbh feels like an invasion of privacy. Please change this!!

Game is very stingy with in game currency. The rates are good though. Problems: • Energy is an issue. You’re given 100 at level 10. Each level takes at least 15+ energy to attempt. It’s nice however that they let you keep all the energy if you lose. However that doesn’t give much room to grind. Takes many runs to build up currency and upgrade materials but you can’t play for long before having to spend in game currency or just waiting hours on hours. • Another issue is the element balance. Fire, water and thunder are KILLING IT! However, the final element forest is complete trash. The characters are bad and none of them do anything. All my teams are solid except for the forest side. Please fix this. • Affinity. Getting materials to increase your affinity levels is insanely hard. You can only buy it with SS stars (which are extremely hard to get and only available with money) and through the secret market. However, all the currency that can be used in the secret market can only be obtained through the secret territory. I cleared all of it and I didn’t have nearly enough to buy anything. UP THE REWARDS. In conclusion, allow players to GRIND. INCREASE ENERGY CAP or decrease energy required per level by half. Also, make currency more readily available. These games end up dying over time because of PAY TO WIN requisites.
