Okay I've managed to survive 80 seconds! The game concept's interesting and gameplay lopp is as simple as fun. However, there's some problems that I must describe:
1. One enemy in your tutorial actually described 2 times (IDK if there's 6th enemy type, if there is you really should change that page);
2. That's not quite smart when you trying to kill enemies with the same elements as they have (like the dude with water and electro element, and you should kill it with water and electro elements), so even when I've read the tutorial I was still trying to kill enemies with the opposite elements;
Anyway, the game's good. Nice work.
