This looks really nice, I think the new art is my favorite part of it, it looks really professional!
Gameplay-wise it's good and it's solid, but I found it really difficult, I dare to say that is more difficult than the DD9 version now that the mosquitoes are flying around. You end up with like 5 enemies on screen and if you try to run from them you will find even more so there is no escape, or even worse if you try to jump from them you can fall on a pit with spikes that you didn't see.
I think you just need to carefully put the enemies and traps on the right spot because everything else works pretty good, give the player some parts where he can rest from the enemies and try to make every important part visible so the player doesn't fall on dead pits.
