i think this game has a lot of potential, i like tower defense so ill try to give this a fair and honest rating. i liked the somewhat simplistic but still nice looking visuals. i liked the sound effects and i think most of the towers serve a good purpose.
i will try not to be too harsh in criticism since you did make this in a rush but i will still point out some issues i found.
the bullets on the towers should try to lead on the enemy, it doesn't seem they do properly and that hurts the gameplay experience some because the towers often fail to hit the enemy.
some music would've been nice but i understand if you didn't have time.
in a game like this where enemies are coming from *all directions* the enemy should be visible to the player equally in all direction y'know what i mean? it's a bit harmful to the player if they can't see the enemy coming in time from above but they can see it coming from the side.
i liked your ideas for the towers but i think blade could've used more range.
overall a pretty solid game with some nice potential for growth! i think it's a good start that could be expanded on greatly :)
