great game!
BTW found glitch, grumpig's sprit is actually invisible and makes enemies hit lose their sprites too
Oops, that happened to you while playing in the browser, right? Sometimes the request to the Itch.io servers fails and the sprites don’t load, which can cause that kind of visual bug. If you refresh the page, it should fix it.
If it happened while playing the Windows or Linux version, let me know, because that would be more concerning.
