Decent start to something. Definitely needs some polishing though. If you choose to continue developing, I would suggest looking into the level of gravity used. It seems like you float down instead of fall normally. Also had a few weird platform issues where I was standing on a platform and when I walked to the right and into another platform, it would automatically go into the jump animation and then have me fall to the ground level. You got several levels in, so it's quite a bit more than a vertical slice, so that was cool. I did not know what the purpose of the stealth meter was until I played a few rounds. Overall, a good entry that just needs more time spent on it.
