We do plan on adding something like that at the end yes! We also have plans and ideas for an infinite level, or a level where you can pick which enemies should spawn yourself!
Yoo, glad to hear. Both of those sound like they'll be a great addition to the game. On the topic of adding things, have you guys looked into adding a mimic chest and/or a quicksand trap to the game? I do think both would work well with the theme.
