wha, how? i know you said something about a physics motor, but really,  h o w  great game btw


When you configure GB Studio on platform mode, you can eject the engine to modifying physics datas of your game ( on GB Studio 2.0) :

Step 1 create a scene of platform (I give to you one of my canvas at the end of the post) and type it as a platform (create collisions zones and all the things)

Step 2 eject the engine

Step 3 find the engine in the folder of your game

Step 4 : find the file platform

Step 5 modifying the initials datas to find goods ratio of physics suitable for your use

Here is the test canvas :

oh wait you're using the beta, right? i'll wait for that to release.

Yes, only the bêta can hold platformer game. But sincerely it's a really stable version, I didn't have any trouble during the built and I' tried successfully to make rom and .exe version,  I'm waiting to a cardridge flasher to make some tests in a real GB.

Hey, love the game aesthetic, can't seem to move past the finding 4 books text, player is locked.

Really amazing style though, it's lovely to see more alchemical aesthetic games :)

Hi, thanks for the comment about the graphics ! I checked quikly and there is no problem for me, I finished the demo without any trouble, I've programmed the keycontrol X to valid text, but it's in azerty keyboard, is there possibly the issue ? you cannot move the character ? HTML players are sometime erratic, maybe you have to clic on it to re-activate it.

Ah, now I know it's X it's working well, feels good to play, I get a little confused wandering around but that may be my fault ahaha

Thanks for the review ! I work on the final game since November, so I don't really realize the difficulty anymore, and I briefly scripted this demo to let people test physic and controls. "I get a little confused wandering around"  It's a little bit the purpose of the game :  Some labyrinthic alchemic castle to explore ^^.  Don't worry, the final game'll be more scripted than this demo !
