Brisk adventuring, excellent 1-bit art and great action gameplay. And I love the sense of humour around the cat, with your owner being proud and congratulatory whenever you get an upgrade.
If there's a few issues I have, they are:
- the "cat" controls can be frustratingly finicky, with a tiny character jumping at high speed all over the screen.
- navigating is pretty brainless: the next objective is nearly always right in front of you.
- the ending did not take itself seriously enough for me (trying to be vague). Great tone for the opening, but kinda weak for an ending.

This is a game I got for free on Twitch a while back, and I'd been putting off playing it for far too long given how much I love Metroidvanias. And you even get to play as an adorable kitty! I'd heard it was short but sweet, and that's exactly what I got, with it taking me a little over 2 hours to 100% the game.

In Gato Roboto, you play as Kiki, the cat of a galactic security soldier who steps on his console during a landing sequence and causes him to crash land onto the research station he was going to check out. Pinned within his own space ship, he has no choice but to send out Kiki to complete the mission in his sted with the help of a cat-sized suit of mech armor you find on the station! It's a cute, silly story that has "voice acting" very very much like Chibi-Robo. It doesn't take itself too seriously, but still manages to be silly-yet-engaging.

The gameplay is a more Metroid-y Metroidvania than a Castlevania-y one. You run around in your mech suit shooting your normal gun and you'll find more power-ups as you go through the game like missiles (which are on a cooldown timer, not a limited thing you need to collect more of, which is awesome), better bullets, better jumps, etc. You can search through 6 areas for both extra health packs as well as palette cartridges, which allow you to change the monochrome-palette of the game to all sorts of colors, from a more soft grey & black, to a harsher (and even fuzzier) Virtual Boy-like red & black, to even an absolutely nauseating Commodore 64-like blue & yellow XD

There are also sections where Kiki leaves her suit and is exposed to one-hit kills, and these are easily the most difficult parts of the game for obvious reasons. That said, the game overall is far from the most difficult Metroidvania I've played, while also not exactly being baby's first Metroidvania. The controls are really tight and the game is really fun to explore around and fight things in, even if the boss battles aren't the most exciting thing in the world.

Verdict: Highly Recommended. It's a short game, but it's oozing with character and solid gameplay. If you're someone without a lot of money to spend on games, you might not feel you're getting a ton of value for it, but if you just want an excellent time to spend an afternoon, this is a really great way to do it ^w^
