I liked Bastion a lot; there were some flaws but overall a great experience. Transistor took this, ran with in, and ran and ran and ran and ran.
For some reason, I didn't realize that the two were made by the same company, but Transistor continually reminded me of Bastion throughout playing it, up until the end credits when I saw that the music was again by Darren Korb when I "duhhed" into revelation. But my point is, the comparison continually stuck in my mind because of all the good similarities between the two.
The music, obviously, is amazing. The visuals were also great. The ability to mix-and-match abilities for different fighting styles made the gameplay always interesting. And the way the voice acting told the narrative was....well, almost eerily similar in style. So all of those things are what I loved about Bastion, and then Transistor went above and beyond that by -in my opinion- surpassing at both the gameplay and the lore.
I absolutely adored the concept of executing turn-by-turn gameplay with cooldown in between; halfway between strategy and action. I loved being able to mix-and-match powers to use them different, especially how the powers had different effects depending on whether they were being used as Active, Passive, or Upgrade. And I loved how, if you run out of health, you don't die, you just lose an Active action. That made things really interesting and far more entertaining because instead of just restarting at the checkpoint, it completely changed the way you had to handle the enemies and added some desperation each time an action was lost.
Maybe this is because I'm a computer programmer, but I loved all of the lore and world of the Transistor universe. Simple things like giving things names like functions like "Turn()" to the more advanced, technically accurate references, down to the last screen which prompts the user between "Start Recursion" and "Exit to Shell". None of it seemed like it was in your face, like the devs wanted you to know how clever they were; it was just everywhere because it's part of the world they painstakingly constructed. And while I'm not exactly a huge fan of Supergiant's monologue style of exposition (particularly the tone of the speaker sounding something like a P.I. investigator), I did love how much they were able to express things about the mute main character with just images instead of cutscenes. (Also, I really like that they had a good reason for her being mute. Small, I know, but nice.)
There were, of course, some small grievances I had. As I said, I'm not a super fan of how Supergiant does their monologue and thus how it exposes the plot; in Transistor in particular, you're thrown in knowing literally nothing and for the first 30 minutes or so, I wondered if I had accidentally skipped a cutscene. After that time passed, I found myself able to get into the world much more, even up to reading the bios of the people that filled it.
My biggest legit grievance is that sometimes the way you mapped out your turn just did not go the way it said it would. Some of this is understandable and something you need to adapt to, like how Cull() hits your targets up, out of reach of some of your other attacks. However, in much simpler cases when an attack just plain misses or doesn't do as much damage as it said....I mean honestly, it can be frustrating, especially if it leads to losing an Action slot. This happened enough for me to be annoyed, but not enough that it ruined the experience of the game.
And lastly, the only technical problem I had is that several times over my playthrough, the screen would get stuck and not follow Red during my Turn(), making planning difficult or sometimes just requiring me to try to start my Turn() again.
All this said, there's nothing that I found that I felt really needed changing with the game. It was fun, it was engaging, it had a cool story and world and even, dare I say it, characters, and even the plot -while nothing to earn a standing ovation- was solid, especially the very end. It's a great game. It's better than that, it's an amazing game. It's not terribly long, about 7 hours for me, but every minute is enjoyable, you don't feel jipped, and it doesn't drag out. While I do feel that Bastion was a great game, I'd say Supergiant has nearly perfected their craft with Transistor and I'm honored to have it as a part of my "Played" list.
