A basic version of Diablo. Next time, try an original concept.

how can i put it nedds a lot of nealy everthing but it was kind of okay thing but yeah add some sond in it then maybe it be a bit better

i could tell you were trying to make a good game and i could feel it trying to show but you need more work and DONT base it around Diablo, in comparasin to diablo your game SUCKs, also, add some sound

Totally agree with TheKnightlyOne.
You need to make this an independent game. This is not so bad as you think it is. Nah, this is good. But lacks work and dedication. Not "improvement", you see - keep it simple. But something like sounds (even if the "blop" style ones) would be a great help. Even better than sounds would be a way to put everything in a single number in the end and put it into a highscore list. It would really draw people to your game, even now. One or another type of monster or map would be great too.
But keep it simple.
This is a good game. Don't fool yourself.

I agree with TheKnightlyOne, there should be custom sounds like the bowss gets a Woosh sound and
the story said rectangles attacked his family yet he is one o_o
Also the Bosses come on too frequently and I almost died but thankfully my Preperation was on :O
Maybe you can change rectangles into creatures like the Big Rectangles turned into a troll and the rectangles that shoot stuff turned into a goblin/bandits bowman or a gunslinger
Try to be more creative but yet good game but needs more improvements :D and i understand that it was only worked on a good 40 hours 3.5 RATE :3
