I played through all levels up to the end - although from around middle of second level on god mode. It was getting too hard, but I still wanted to check out further levels, enemies and dialogues, they look so nice. Good job! Some thoughts:
- Visual style is great. All the elements (arabianesque, faibanks-style silent movie adventure, hackel inspired monsters, sepia toned down colors, melies-like floating skulls etc etc) it works really well together. Deep sea monsters are especially nice idea, they look beautiful and scarry.
- Dialogues are also ok, funny and not too complicated, they don't interfere with the gameplay too much. Animation of carpet is really cool, I love how the feather on the last guy hat is moving high-speed. Music is 10/10, mix of of arabian sounds and harsh glitchy electro works for me like charm.
- I'm not entirely sure about size of the carpet in terms of gameplay. It's really hard, nearly impossible to avoid some of the enemies on further levels. But if you want it uber-hard, then don't change it, because visually speaking it's totally ok.
- Another thing I like here is that during cutscenes you got fast forward option instead of skip. It's great. It gives player option to make it faster, but also be sure that they are not missing anything huge.
- Bosses: I dig them 100%. Funny and challenging, but also not an overkill. Rainbow pegasus boss brings some visual difference at the end - it's also cool idea. Ending itself is funny and satisfactory.
All together, as I see it - there are a lot of pros and almost no cons. Congrats. Easily one of my favorites playtests from recent times.
