Become the Moon is a single-player deck-building auto-battler with roguelike elements, where you construct decks of minions, spells, and relics to battle enemies in automated turn-based combat. The game’s core loop involves drafting cards after each victory, optimizing board placement, and adapting strategies to overcome a gauntlet of foes. It draws clear inspiration from Hearthstone.

There are over 140 cards to experiment with

Fun fact, there are over 140 cards to collect for your deck, alongside multiple synergies like flying, exhaust, battle-focused spells, and one-time effects. On the other hand, relics provide passive buffs, such as giving flying units a bonus when they attack. The goal is to create powerful combos and reach the final boss. I’ve been experimenting a lot with flying cards; they have a 33% chance to dodge attacks and create interesting combos with quick attack cards, which allow an adjacent card to attack instantly.

However, the biggest problem is the high randomization of cards. You’re forced to take cards for your deck because skipping them costs health (only the first skip is free). This means you sometimes have to take cards or spells you don’t want or need. This system does balance the gameplay, meaning you can’t just pick cards randomly; you definitely need to think through your choices. Once you defeat all the cards on the board, the enemy hero takes damage from your remaining cards. If that doesn’t defeat them, your hero then battles the enemy hero directly, which can also deal significant damage.

As mentioned, combat is automated, with minions attacking from left to right and targeting random enemies on the opponent’s board. I found this sadly too chaotic; you’re never able to pinpoint what will happen. While this unpredictability can be a good thing, the random targeting also somewhat ruins the fun, as it introduces too much luck and prevents a truly prepared strategy.

Deck-building is solid, drawing inspiration from Hearthstone

Become the Moon offers 10 character classes, each with unique starting cards and bonuses, adding variety to playstyles. You’ll need to unlock these classes by defeating them within the game. There’s definitely a lot of content to explore; it takes several hours to fully grasp the cards, but once you do, you’ll see how fun it is. The cards themselves are well-designed; some are balanced, while others less so, which is common.

Your strategy typically involves placing and swapping minions before battles, and using spells, but the auto-battler format does reduce micromanagement In other words, analyzing the enemy’s board allows for certains adjustments, such as placing a high-health “taunt” minion to absorb attacks. Mechanics like shields (blocking one attack), taunt (forcing enemy focus), and deathrattle (effects upon death) mirror Hearthstone.

I particularly enjoyed consistently buffing minions on the field using multipliers and bonuses for health and damage. You can also pick spectral cards that persist throughout the game and can be used once, such as to gain extra mana or draw more cards. The game provides fun ways to tackle different challenges. While not revolutionary, it’s engaging and keeps you hooked.

Fans of the genre should definitely pick this one up

The roguelike features aren’t very evident in this game. My biggest issue is that enemies are predetermined; you can’t choose who you fight, which is a significant drawback. Every stage presents similar enemies with the same cards, and the “bosses” are no different. While fighting the same bosses might be understandable, having identical regular enemies truly harms the game’s replayability.

The graphics in Become the Moon feature a 2D cartoonish dark fantasy style with various colors and charming character designs. Minions are expressive, with detailed card art that adds to their personality, and smooth, visually appealing battle animations add flair to the auto-battler format. While the visuals prioritize readability over spectacle and aren’t groundbreaking, they’re engaging, though some card designs feel repetitive, slightly limiting variety.

In the end, Become the Moon is a solid deck-building game. It won’t waste your time, especially with its speed-up option, and the best part is undoubtedly the card-drafting phase. If you’re wondering whether it’s good, don’t hesitate; it’s a decent and well-crafted title, clearly made by developers familiar with similar games. While replayability might be a bit questionable, the numerous heroes available do help extend its life. If you’re already a fan of the genre, this one should definitely be in your library.
