I loooooove this game
Great game, I'd just make the first option in the main screen "Continue" instead of "New Game"
This really is a good and fun game
i love this
I KILL EVERY SINGLE ENEMY ON THIS DEMO
This game is a masterclass in how to teach game mechanics by showing rather than telling. Wonderful work!
one of the best game I've played
I just created the account to say, this is the greatestestst gamestesttst ever, it's so fun and whimsical
i'm on mac, and i can't use the gun
Are you using a controller or keyboard? On keyboard shift should work.
keyboard
i can do it now
maybe my mac is at fault
GOOOOOD Gran juego me gusto mucho el estilo y la jugabilidad, espero ver el resultado final :D
After Beating the Demo I truly believed this game is quite a masterpiece I love how you used the wine up boot from "Super Mario Bros 3" a very good mechanic along with the infinite gun shooter (I call it that for now) is a very nice concept. The Boss of the last level Rollin Rick has a extremely good dialouge with his Texan Accent also I like how you are able to use a checkpoint that both replenishes your health and gives you bullets on top of that I love how you can find gold Coins I will stick with my gut once more a wonderful 10/10
(Editors note I don't really know how to you revolver out though. If you make a Sequel can you make a Gameboy Advance style for Kero Kero Cowboy 2)
To the person who made this your a frickin genius to make a game like this as a 11 year old I greatly give this Nintendo seal of Approval we need a real game like this the platforming with a little inspiration Kirby is really fitting with a frog Cowboy an easy 10/10
The demo was so much fun! <3 Really looking forward to the finished game.
Thanks! Full game drops May 7th so you won't have to wait long ;)
Felt just like an old Gameboy Color platformer in all the right ways. Looking forward to the full game.
Absolutely loved the demo & I cannot wait to play through the game when complete! Music is spot on!
Will definitely be picking this up when the full game is out
This is really fun and well polished. The music is fitting. The backgrounds and sprites look great and have good color choices. It’s so cute that the frog holds their hat when jumping. The game has a good Kirby, Mega Man, Castlevania feel. The gameplay is fun and challenging. Keep up the great work.
Awesome looking game, catchy tune, fun to play! Congratulations on the kickstarter aswell! Would you mind sharing some more infos – did you compose the music and create the artwork? Would love to also learn more on how you did the kickstarter including production of physical devices :) Thanks for your great game!
Awesome game I can’t wait for the full release! Worked great on my analogue pocket but I couldn’t get the rom to work on my everdrive gb x7, this has happened with some GB studio games for me in the past. Do you know why or how to resolve it?
Thanks! Also that's super weird, I have an Everdrive GB X7 too & it works great with it along with every other GB Studio game I've tried with it so far 🤔 Maybe it needs a driver update?
I really enjoyed this game! The mechanics (boot/revolver) are super intuitive and give the player a chance to figure it out before explained. I thought the campfire mechanic was cool too. Top it all off with the art style, and I am excited to see the full version of this game!
Thanks!
Very cute game, it is a little mix of yoshi and kirby.
Thanks! Much more to come :)
the fact this can run on a real gameboy proves that human evolution truly evolved into this
humanity's true purpose 💪
i love this demo
please do the real game 🗿❤️
Thanks, will do!
Bonjour,
Merci pour cette démo qui est vraiment bluffante, magnifique travail!
Hâte de voir le jeu complet que je vais tout de suite Kickstarter ;)
merci beaucoup!!
I can't really explain why but I've been playing 1-1 to clear it as fast as possible for about 5 hours for the past 5 days I think. For some reason I'm hooked to speed running a gb game's demo, send help please.
lmao that's amazing. First KKC speedrunner!? I'm excited to see what you can do when the whole game's out!
Easy, Intuive, Great Visuals, Great Music.
A nice mix between Kirby and Mario.
I discovered this on reddit.
10/10
Thanks for checking it out!
This is real nice
I loved it , can't wait to see the completed game < 3
I loved it!
Really nice Kirby-style platformer! The music was fantastic too.
Simply wonderful, I love it.
Cute art style, bonus points for a frog wearing a hat. Appreciate that you included support for controllers, too many games don't include it
This was a fun little game! You should disable the gun during the boss fights or make them immune to bullet damage.
This game is pretty cool
this game is adorable! i love the way it looks, and it has so much personality. can't wait for the full game!
This game is awesome, good job!!! I hope you make another one
i loved the game!
Such a cute little game, very nostalgic
I love frogge
