Very simple. very cute, very nice :thumbsup:!
I suppose you are new to game developing so I will try to give you at leat some advice like the others (even though I can't say I am highly expirienced either :stuck_out_tongue_closed_eyes:).
I saw many comments on which element in the game is a must have, and many said audio! You can have an amaizing graphics style desing gameplay ect. but without music or any audio it will feel bland and horrible. I've now wittnessed games like this and they had a bad impression on me. In contrast I've seen games with very simple desing (litteraly circles and squares) that had most of the effort put into music and those game were fenomenal to play!
Next, you had a very simple idea of an gameplay but that doesn't mean it will be bad! This only has a lot of potential at it's current stage. Only thing I will say that I saw maybe a slower sword rotation speed to add difficulty or more enemies popping onto battlefield over time. You probbably would have done somthing simmilar or even better if you had more time I suppose, as everybody would.
First time I've made my game in three days it was a nightmare! I'm also programing in Unity and then I didn't know that much. I was constantly watching Unitys manual or youtuber Brackey's :smile: for help and I lost tons of time even though I had so much more to implement into my game. Now I can say I'm on a different level then back then and because I practised making games (even to an unfinished state) I can now build games faster and more polished. This means just that you need to practise and eventualy this will become easier and much more enyojable!
This is all I could think of in this moment. Hope you had at least little fun on this event! :smiley: Maybe I'll see you on LD47 again?
