- Decent core gameplay.
- I think too many enemies spawn a bit to frequently to start with.
- You need more sounds. The crystal picking up sound is fine, but it's the only thing in there.
- More weapons or mutators for the spells would be nice, but I'm sure you have those planned.
- Different enemies with specific weaknesses to ice or fire would help force the users to use both spells. As is, I overused fire and didn't realise I even had ice attacks until several minutes in.
- Some controls UI would be nice, especially to see what things I've equipped. (Kinda like HoloCure)
