Overall, a nice sturdy entry *^* Really loved your work with particles - fireballs were the most juicy thing for me. Cute visuals and interface - a pleasure to my eyes)
Balance, however, needs a hard polishing. There's no indication of where enemies will spawn, and character gets surrounded too quickly. Hitting an enemy, as for me, feels not impactful, not juicy enough.
Alsoo, it would be a great idea to nerf the first grave a bit - just to give player an opportunity to get used to enemies behavior, etc.
But, as I said - loved it! Thank you for this entry)
