Crawling Dungeon Alpha Windows, Mac, Linux game

I haven't been working on this game for very long, before then I had VERY little coding experience. I have used online tutorials to make this. If you experience any problems while playing let me know and I'll work on a fix!

About the game

Crawling Dungeon is a top down 2d rpg with a twist. Their is no items! The only way to get stronger is to level up by killing mobs and bosses. There will be about 10-20 dungeons with mobs and a boss at the end, as well as 10-20 boss rushes. As well as that I plan on having 1 or 2 raid like bosses that have complex mechanics and take a lot to kill. So far you can only access the first 5 campaign dungeons and nothing else. When you start walk up to the NPC who is your guide and press "F" and he will give you the basics. At first each dungeon is the same thing, kill enemies, fight giant virsion of them as a boss. But the last 2 are different. The 4th dungeon has a tactic for the boss, and the 5th boss has a tactic and instead of being just a giant virsion of what you versed in the dungeon its a new creature. You can find out the tactics in the trailer video. I'm trying to make the boss fights more unique as i go but it all comes down to my ability to code, if i cant figure it out myself and cant find the answer online i wont be able to do it.

Pricing

I have made the alpha free. The beta will also be free so you can all play that when it releases. For the full game I havent decided if its going to cost, I'm leaning towards it costing, but it wont cost much.

Please do give my game a try, should take under 10 minutes depending if you rush it or not. Please give me feedback so i know how I'm going, just dont be to harsh if you dont like it, this is only my first game.
