Hi, thank you for your feedback. We have updated the game a bit according to your points, please play it again and see how it feels now.
Here is a special challenge for you from our side: complete the game up to Level 25 in one go. The hard part is, if you die even once, you go straight back to Level 1. It is a tough challenge.
One more special tip: also try the Co-op mode with a friend. That will be the best experience for you, we think you will really like it.
Do share your result here. Good luck!
