I definitely will be providing a rating and feedback for your submission; congratulations on submitting to the jam!
Thank you for the thoughtful suggestions! I agree, a combo system would definitely make this more fun - and it's so close to having something like that it's a shame I hadn't thought to add it in last night! Special attacks w/ key combos is another interesting idea; for that I think I'd wanna change how the input works generally in the game.
Thanks again for the comment! This jam was fun; I'm looking forward to checking our your game. :)
