Please don't take this comment as being pedantic - I'm playing through the latest demo and just wanted to make sure that the text is grammatically correct.
On the difficulty screen at the start, the Super and Easy difficulty text would be more grammatically correct if it read "Player takes and deals more damage" and "player takes less damage"

English is stupid like that... "player takes" if there's one player, or "players take" if there are multiple players. I know it's super minor, and again I'm not trying to be the spelling police lol. I'll comment anything else I find as I play through.
[EDIT] "platform" should be "platforms"

"each others" should be "each other"

"certain wall" should be "certain walls"

"projectile" should be "projectiles":
