Its good.
But it needs more/better spells. Maybe instead of losing your spells every level, you can upgrade them to make them more powerful. Because each one is expensive and doesnt give that many uses. The only ones worth buying are Speed & Power and Sheild. The fireball spell or whatever has too little uses to be really effective and the lightning spell i just dont get, it seems to me like it should take spread far and take out one thing per bolt, but it will hit one or two things and waste all the bolts, why?
The Enemies are good they start off easy and get harder, but then they get ridiculously hard and amass in huge numbers as you progress. Maybe if they dropped like health upgrades or like armor or something. Also, they give a minimal amount of gold and if you plan on using alot of the spells it just doesnt cut it. Plus if this is a war for the title of ultimate mage, shouldnt they fight each other too? or maybe you should have some allies?
The menu bugged me, it appeared whenever i would move my cursor towards the edge of the screen and would make me buy spells i didnt want to purchase. If it worked just on the arrow, or maybe it was up at all times that would have been nice.
Its a good game, fastpaced and addicting but i really hope you make some changes cause it would make a very nice game if you did.
