I love this game, but oh my god is it cringe to play in front of other people. This is the kind of game you play by yourself and never talk to anyone about. Which is a shame because the puzzle solving is addicting. I feel like if the game leaned more into the fast paced puzzle solving game mechanics and less into the role playing elements of its convoluted love based plot, then it would have had much more success. However making a game about playing as a cheater who climbs blocks in his underwear at night is just too bizarre and niche to have sustainable mainstream presence in the long term. If you can force your way through though, it’s a very fun game. Based

This game is evil.
You're stuck with a shitty deck, while every random fucking NPC has a competent deck with every staple in existence.
You can't even play something decent until late game and synchros are basically post game stuff.
The clone battle at the end is absurd, 4 meta decks including tier 0 TeleDAD vs your playground random bullshit go deck (or Lightsworns).

If you want a Synchro deck in early game you can farm the naturia girl in front of the cardshop in Satellite, there's a chance she gifts you Naturia Beast after beating her. Get one or two of them, get some Earth support from the early game packs like Gigantes (it mixes super well with your Mecha Bunnies) and after a few hours you'll have an Earth Synchro deck with the super powerful Naturia Beast.

Gravekeepers are also an option and the kid inside the card shop can gift you Commandant and Necrovalley.

Or you can just test your luck and progress until the Lightsworn pack is unlocked and beat the game with them like most people.

I went in expecting a pretty cut-and-dry shmup, and was pleasantly surprised to learn that there's a little more under the surface, even with an incredibly narrow range of difficulties for having 6 options, down to "child easy" and "monkey easy." The complexity comes in with the Dragon Shot mechanic, where you launch your dragon forward, temporarily separating it from the rider in a burst of damage and then making it into a sort of stationary turret until recalled. To survive Dragon Blaze, you need to use the Dragon Shot frequently, but this becomes a challenge when now you need to keep track of the location of two entities instead of one. Provided, the dragon will not take damage, and will continue to shoot while it's separated from its rider, but the game provides bonuses for using the Dragon Shot at opportune times, extra coins drop from enemies, some enemies drop special point boosts when hit with the DS, and every boss has a very brief animation where they're prone to being one-shot by the DS, usually in the midst of a cloud of bullets that make navigation even more difficult.
Mechanically, it can feel a little dry compared to other shmups, especially with more modern advances in the genre, but it's charming in its simplicity, its art style is great, and goddamn it it makes me think of Panzer Dragoon just a little bit so call me biased if you must.
Its one very very noticeable flaw is its absolute terrible UI, it feels right out of a mobile game port and reminds me of the early days of the Steam Chrono Trigger port that was just straight up the iphone port with shitty default fonts and all
