Very cool and interesting concept and overall fun game!
I really like the implementation of the 10 seconds theme and its mix with the other game mechanics. I think that some changes could be made to improve the overall game. Some of these changes include a visual indicator of the 10 seconds counting down, keeping the current abilities state when you die rather than resetting them, coyote time, and some menus! - (I understand why these changes most likely don't exist as there is a time limit with the Ludum dare game jam, although, in the future, I recommend you keep these changes in mind whenever you have some time for polish.
Overall keep making games as I can see potential considering what you were able to create within the confines of the Ludum dare game Jam rules. I would love to see what you could do if you were developing a game for steam!
