Ah, sorry about that, that enemy really shouldn't appear so early in the game, but as you probably already know, we just didn't have enought time time to balance everything properly.
We are working on a post-jam version with all these issues fixed (and maybe some extra features). But in case you want to try again without having to worry about getting stuck with the super moth, press SPACE + F to one-shot the enemy. This is obviously a leftover developer option and not intended for players to use, but we can see the frustation with this particular enemy and feel like having to end your run because of it is really bad. So, good luck reaching the boss! ;)
And thank you for your comment!
