Day 1: Planning the game I'd like to make and writing everything down

I wrote down the game idea I had in my head. The game will be called "Inside The Data Tunnel". The objective will be to ward of as many malware (viruses, trojan horses, ...) as possible in 25 levels without dying. Only neutral / good data may come through. The less bad data comes through the better the score. The player is supported by allies. Both the allies and the player either control a Micro-Spaceship or a Micro-Robot. The entire game can also be played in a two-player mode, where there will be more enemies but also more allies. The data will come in from the left and go to the right. The playable area will be 1024 x 650 px. There will be 4 soundtracks and a dozen or more sounds. The malware gets stronger each level. The player(s) and his/their allies can only get stronger if they shoot and kill malware. Occasionally, power-ups / gems can be collected (they will be dropped by the neutral / good data), which can give a boost for a specific thing, such as speed, auto-fire, double EP, ... Well, so far, so good! I will now continue to design (draw) the Micro-Robot, Micro-Spaceship and the malware aswell as the neutral data. I am going to use Inkscape for this task. I will probably also do the other drawing-related tasks. After that, I am going to write the basic code to get the game going. Although I am on vacation this week, I will be quite busy tomorrow and the day after that, but I hope it won't be affecting me too much. I intend to make music and the sounds on Wednesday/Thursday. OK, that is it from me so far! Thank you for taking your time to read this. See you!
