Thank you so much for spending some of your time to try out my game!
I sort of explained some issues you mentioned on my postmortem, but basically one of my biggest problems was getting the rewind mechanic to work at first. Also, I was the only guy to work on this. Originally I was going to have three of my friends to join the jam, but two of them had their hands full and the other one didn't respond to my message on time. Some personal stuff got in the way as well, and eventually I had to cut some content. The respawn point being one of them.
I'm also glad that you enjoyed the soundtrack. There was going to be one solely for the gameplay, but like I mentioned, I didn't had the time.
