The cursor is too small and camouflages with the background. The in-game instructions should've included controls, since it's not immediately obvious what they are, but it immediately dangerous to not know them. The electric powers seems to be useless, the ice power has really ambiguous range and not enough healing to matter unless the player is using it right from the start, and the fire ability is hard to aim with the cursor issues. The enemies reaching the player so quickly from off the screen makes it hard to tell if it's possible to defeat any without taking damage. The dialogue takes too long to continue, making it hard to tell immediately whether the game is working.
Overall, I think the visuals are good and the core idea is interesting, but not really anything else.
