Very Creative, I like it! The game is extremely difficult though. The egg shaped body makes dodging those blades on the second level almost impossible. Good thing there's checkpoints. This game makes dark souls look like a cake walk in comparison.
The game requires so much precision, that I accidentally resized my browser window many times. A full screen desktop build would alleviate this problem completely.
Another thing to note. I'm gaming on a 144hz monitor, and it feels like the game is in fast forward mode or something. I played your other amazing shooter game with gnomes, and that games speed felt much more natural. I watched your game development live stream on Youtube and the gamespeed looked much more natural. When I make a game using the Unity game engine, I remember to multiply my movement speed by delta time. That way the game speed is exactly the same no matter what frame-rate the player is running the game at.
Otherwise I really enjoyed this game. I'm not going to pretend like Chick Magnet or that Cupcake pooping goat game compares to your master piece shooter up gnome game. I'll look forward to playing other games you make in the future.
