It was hard but I could beat it!
The controls might need some tweaking, the game itself doesn't tell you how to open doors or grab items, although that might be my fault for not reading the description.
Also, I had to restart multiple times because Shrek's corpse blocked my way to the key, lol.
It's a very nicely done game otherwise, I like the graphics, it fits the theme very well and I had fun playing it.
