Though I would say that this game has alot of promise it has some glaring issue's with it's design I've gotten glitched on the first level which may be a bug you will have to address if you want to continue development of the game since It's a game breaking bug seeing as there is no pause menu or way to restart the game which means I would have to restart the whole game to try the level again. another point is that this is not a metroidvaina which is what the jam is based on it also this feels like this would better as a html game then a downloaded one since gdevelop allows for html5 exporting but overall I would say that there is a soild gameplay here which could be expanded on. (though even if it is not the genere the game jam is meant to be)
