We actually wanted to make a small title music but then decided to do just ambient. We knew we were on the right track here ^^
Unfortunately we lack experience in game balancing because this is our first game we finished. We had a few testers before release (that’s why you have a checkpoint in level 2 for example) but I agree that we could have changed the box colliders a bit.
But thank you for playing our little game and I hope you still enjoyed it despite your many deaths.
