I've seen some of your tweets the other day and it looks quite interesting!
I think it might be useful if you described your game a bit more, as in how you actually play it and how the mechanics work and what kind of gates there are etc.
Most of the text here is (and on the Kickstarter preview) is largely just marketing blabla, about how the game "feels" and text about yourself.
Personally I'd be rather careful with Kickstarter. Sure, sometimes I've seen people get really lucky, but more often than not, those Kickstarter that succeed already had a small to large follower base, meaning that there were a couple hundred people out there that knew about the game and a core group that is actively following the development of the game.
While €3000 isn't that large of a number, you'll still need around 800-1000 people to back your project, which means you need to reach a multiple of those 800-1000 people who'll look at your campaign, because most will just keep browsing on.
Finally, make sure you've considered your rewards well. Not sure what your limit for Picasso is, but promising 5min of your time, can accumulate rapidly. Are ready to draw 8+h for 100 people?
As for your largest reward, are 30h of your time really just worth €350? Can you attest somehow, that your C++ knowledge and teaching skills are even worth 30h? I feel like any sensible person will or at least should stay away from this reward, because it's a high-risk/low-gain investment. I'm sure that for €350 one can find C++ courses taught by people who can show that they have the experience to teach and talk about C++ fundamentals. (This is constructive feedback to make you reconsider either your "selling" strategy or change the reward, please don't take this personally.

As a student, I unfortunaley do not have any real financial ressources to rent dedicated servers for the level-database, or a custom web-page, or the Steam-Greenlight fees.
You and I both know that this is not true. If you can't afford the $100 Greenlight fee or pay a few € per month for a simple VPS, then you're doing something seriously wrong with your time or your money. I know, because I'm a student myself and I run my own server, plus multiple domains and lots of other stuff.
Don't invent facts that are not true, it will just make you less trustworthy and as Kickstarter is based on pure trust (we give you money and trust you to keep all your promises), it will make things a lot harder.
And as a final tip: Activate spell-checking in your browser and set the language to English. In your post here and the text on Kickstarter contain basic spelling errors.
Keep up the work and I look forward to seeing more of the game!
