I bumped into Tooth and Tail after watching a GDC talk about the game's art direction, felt compelled to give it a try, and was pleasantly surprised! Beyond the amazing and charming artwork, I found this a refreshing take on the real-time-strategy (RTS) genre.
My favourite RTS is Total Annihilation, where you can spend a *ton* of time first building up your base before you go on the offense. I'd say Tooth and Tail is on the complete opposite end of that spectrum: games tend to be short (5~15 minutes, for most single-player maps at least) and you'll need to fight back early-on. It took some getting-used to, and the later maps in the campaign can get pretty intense .. so some maps I had to retry several times, but I was ok with this because the games are so short.
Some would say the gameplay is simplistic; I would call it streamlined, and I like it because of this. Just the bare essentials of an RTS .. to the point where the game is made to be played with just the keyboard or a controller .. and there's something very enjoyable about that. (FYI - the default controls do use mouse buttons .. but mouse movement isn't used at all, so it works best for me all-keyboard)
I also really liked that the game doesn't hold your hand story-wise; there are 4 different factions and the bits of dialogue assume you already know everything from the get-go .. so you'll be pretty clueless at first, and everything only starts to make sense gradually. I also enjoyed the "Banjo Kazooie-style" voices to add a distinct character to each of the units.
I only have a couple points of improvement: it's cool that the maps are procedurally generated, but there often are very narrow pathways that are visually hard to read, which makes navigating a bit finnicky sometimes. You'll also need to learn about each unit mostly through trial and error; would've liked something to speed up that process.
All in all, whether you're a newcomer or veteran RTS player, I can easily recommend Tooth and Tail!
