Hell Yeah! Slay the Spire meets Tower Defense is the way to describe this game.
If you like deck building roguelike card game then you must try this game, even though in my humble opinion i'm not a fan of the monsters graphic but that is outweighed by the replayability of the game. for the price of $13 (Rp.206.999) this game is very worth to try if you looking for good replayability.

One thing that make me attached to the game is there is sooo many ways you can make your own combo units and spell so you don't get bored getting the same combo and using the same deck over and over again, even you can turn 1 kill the last boss! in the end it's about the synergy of the deck from the units and spells, i have tried so many deck combo ideas and still found another one while i'm playing. The RNG is somewhat manageable compared to other deck building games in my opinion

The difficulty of this game is very challenging in higher covenant rank (ascension rank in slay the spire) but you'll learn through it, sometimes you'll get through normal fights very easily and then obliterated at the boss fight and vice versa. even after achieving highest covenant rank there's still challenges that is unique and still fun to try if you will and every run is recorded in your history run so you can check every run you had.

TL;DR
Pros :
- Good replayability
- Very broadly combos
- Challenges are challenging

Cons :
- Animation is too lifeless
- Challenges are challenging too fast
- Last Divinity DLC is a must for a full experience

If you still unsure about it, get it while on sale is totally worth it

Slay the spire was honestly one of the first in it's own genre to set the foundation of what a rougelike cardgame should be. It had its downfalls, people talk about RNG but I could defo see the codeware being managed to set you up to follow a strict path to victory, with one little mistake or step outside of what the game wants you to do, setting you on a path to failure.

Monster Train isn't like that.

This game ENCOURAGES you to experiment, and it doesn't make it hard for you to win your first few runs. But, it does make it hard to keep a streak of wins.

Each run is short and sweet, fast paced and if its not fast enough for you there's also a speed up button to flow more through the animations.

I look forward to getting addicted to this.

I think this is my first review ever at steam. This games definitely the best game I ever played. Very diverse across the 6 clans. Summore add with main and sub clan. But a bit sad since there will be no major update beside the last divinity DLC
