Aye,

Currently I´ve missions planned like "Plant a tree (easy)" and
"Win a price in a competition (not so easy)".

However, I need some missions which challenge the player more.
So I would love some suggestions regarding the gameplay, especially regarding the mission design.

you could add "einen haufen raupen" which try to eat your garden, and than you get extra score if you use wasps insted of poison to defend..

to make a really outstanding and not just the same crappy sim, like the others on the market, you must add something insane.

Add an littel earthquake and poison waste in the ground. Some strange things from the pre owner of the garden. And then the player has got the right to go to a lawyer and to fck the pre owner by justice. Just to get some money to buy better tools for the garden.

Thanks for all your comments and suggestions.
The publisher is very pleased by the mockup and our current mission design.
There will be a career mode as well, so you can play freely without any constraints.

It looks like we are on the right path.

Update:
It seems to be sure that we got a publisher for a rather similar project.
Shade-c has done a good job - the demo is stable as a rock and works on different PC´s and laptops.

I would like to give you some insight behind the scenes, but we have to wait for the nda.

Some shader wildness:

We´ve received the publishers contract.
Believe it or not: We were able to sell a concept without a playable demo!
