first off nice job on the main menu animation. The biggest problems I ran into well playing were the collider on the player let him fall of ledges unless he was pretty much right in the middle of the smaller platforms. A hang timer for jumping would make it feel more responsive but that is not a major issue. a variable jump height based on how long you hold the jump button would make your game feel that much more tight.

When I was fighting not drink blood on the third level it made me fall to my death when I fought off the urge lol.

But other then that good game to you and your entire team to bad not many people are plating and rating it those far hope some more play it before the rating times ends.

Love the menu animation! A bit too challenging too fast. Also it helps a lot if you can export your game for web as it is fairly easy to do and more people will play it.
