First time playing this game, I didn't read the games page so it was a truly blind experience.
I played in regular difficulty, at first I was lost, because I used my weapons and didn't deal too much damage, but then I realise the game was like magicka and start defeating the enemies. The melee weapon felt weaker compared to the gun, with the gun I just go for example: full ice and one shoot the fire drones plus it freeze enemies. A basic tutorial will be helpful, it doesn't matter if it's only text, it will help new player a lot.
This project looks promising so far and the visual effects are nice, no complains in that department, keep the good work.
