Thank you very much for playing our game! We're really glad that the heart and soul we've been pouring out the last month is noticeable to you!
Adding more checkpoints was a decision that we weren't fully sure about, but we're glad it was able to let you enjoy more of the game.
No worries about not beating the boss! It was very hard even for some of us to beat it, but we didn't want to change it up too much when we were so close to the deadline, when an unexpected bug would be deadly. Hopefully you'll be here if we make a future release, which will definitely feel more polished after having much more time to test and balance!
