Hey guys,
I have been reading your feedback and as a result added Keybinds and more Content to the game.
First let me say that I'm thankful for your patience. I can understand that only 8 Maps is very thin compared to other tower defense games. In this patch I'm going to add two new maps to the game, one in the forest and one in the ice region.
For those that want more content, don't worry, there will be more content and updates in the future.
Skillpoints CAP is 666 now! Enjoy!
Several new Items have been added to the healer, there is also a new Keystone on the skill tree.
Keybinds
This might not be the perfect solution. But at least you can now rebind keys. I hope you like it.
New Maps
With this patch there are 10 maps in the game now, and more will be added over time. I try to make the maps somewhat unique so it doesn't feel like you are repeating the same map, just with different paths. 
Thank you again for your ongoing support. I hope you enjoy the game, and thank you for playing ːsteamhappyː
Cheers
