Thanks for playing! I didn't think anyone would find that easter egg, I'm glad you explored a bit to find it.
>I think the game would look better as simple drawings, and not necessarily pixelart.
I agree with you, I realized it not too long ago. If I started to dev the game from zero again I would try to use the style in the tutorial or at least adapt it to something easy to animate. Sadly at this point of development moving away from pixel art would be very difficult for a lot of different reasons.
Maybe for a sequel or remaster if this game ever gets succesful enough.
