Hi!,
Here's a list with the roadmap planned, do not hesitate to send suggestions, I will consider all of them.
Right now what's in the list is:
-3 new playable characters
-3 new dungeons
-5 new enemies
-3 traps
-modified UI
-new sounds
-overall polish of special effects
-tutorial for the game
-tutorial for the editor
Those are the things will be part of the final release to leave early access. I will be releasing updates gradually during the first quarter to have all that's in the list ready.
Remember, the price will be raised by that time. So, grab the game while is cheap :)
Enjoy the game!
