Hi! Thanks for the feedback!
I plan to revisit the game and finish it. I think it has a lot of potential and I haven't seen the "use dead body" mechanic in many games so that might be a novelty, but I have to polish the rest of the game.
-Add more art (the environments look plain because of course I didn't have time to make a ton of art for the jam, all programming and art was done by me so that took a lot of my time)
-Add more mobility to the knight (pogo, dashing, sprinting so people won't get bored while traversing the levels)
-Add more things to do with the bodies (use them in several ways for new traps, use them as shields against archers, feed them to lions so they let you pass, etc..)
-Add more enemies. Archers, mages, sub bossesm probably divide the castle on giant levels with bosses at the end of each level...
-Add power ups (for recovering health, stamina for longer sprinting times, maybe even to unlock special abilities like climbing, dashing)
-Maybe even a way to charge up your throw so you can throw the bodies further away.
So yes, this is helpful. I agree that using E while moving (mainly right) is a problem. I'd switch it for a mouse button, probably revisit all controls since I'll be adding more mechanics and adding support for console controllers.
In any case, thanks a lot for your feedback, I'll be sure to read through the comments when I come back to this and take everything you and others said into account so this helps a lot. Thanks for playing it!!
