Nevermind figured it out (you need to click the arrows on the page itself), for the future add some indicators letting people know the controls as I'm sure many people are gonna be stuck
Viewing post in Don't Break Your Mouse ! jam comments
As my project was submitted at the same time to two other game jams which require the use of a single button, I completely forgot that such gameplay would not be intuitive to the players of the "Palette Jam 2". Entirely my fault for not having indicated it directly in the game. Nevertheless, it remains interesting for any player to read the details in the description page of all the games, because it very often contains gameplay indications and various instructions that help to better understand the game. Like what I've wrote "[...] left click of the mouse ... but with this button, you'll have to control all the others buttons in the game. , [...] ". But, yes you're right, I could (and should) have added a warning / explaination directly in the game. I just hope that the other players will read the description text, or this comment ^ _ ^ Thanks for trying my game.
