Absolutely love the player sprite, so damn adorable! I'm a sucker for hoods and scarfs and cold clothes so this was an easy win for me haha.
Using the portal gun was really satisfying to say the least and it was so cool mixing it with platforming and puzzles.
No real criticism from me other than it is possible to get stuck in some places, such as if you are a clown like me and jump down in to the "Shoot beyond" area before acquiring the portal gun or getting clipped into tiles when going through a portal.
All in all though, great game and great job friend! :D
