I've played the game a little and is preatty good, a really chill playing style but also challenging.
The basic mechanic of the game is really cool, i really enjoy the ability to switch between brother, the only thing thant threw me off is that the spacebar change the playable character and not make you jump.
I would suggest you to change the jumping button to the spacebar and the button to change brothers to something else.
I hope that in the future releases you will add some SFX and other consumable items.
It's a solid game, good work guys!
