I like that it pays off if you don't just shoot each and every enemy. It makes you wanna pass them without being hit - without shooting them. It's a bit like stealth games but in a completely different genre. Good take on the jam's theme.
The owl is definitely the enemy to avoid, for that's the hardest one to beat in the boss level. World 3 is amazingly hard - but even that one is doable.
Artwork is ok, animations even better. I especially love the fox's movements. His jumping and lying down are just perfect.
Good soundtrack that fits the theme and adds up to the gamer's experience.
Nice little gem! Thank you.
