Algodoo

Nice game, but it needs more work (if you want to make it a better game). For example, add a scoring system (maybe add 100 points each time the snake eats the mouse). Also, maybe add a timer. For example, the game runs for a certain time period (5 minutes?) and then automatically stops. User tries to beat his/her previous high score. There are other things you can add such as scorpions that try to kill the snake, and birds that try to take the mouse away, etc. Just a few suggestions!

I wanted to add levels, each time you ate mouse, you go to next level
You will have energy bar, quicker you move, quicker you use the energy, and also passive energy drain will be higher each level, so you will have to improve otherwise, you spend too much energy flapping around and exhausting the snake to death (Nice scoring system, right? )
My main concern is controls, I can easily make realistically moving snake, quick precise attacks, but Im using 4-axis controller from Arduino and old RC radio transmitter, but I'm really bad at controlling it with keyboard
