Tutorial-wise I think you need to assume we are 5 year olds that have no clue how a computer works. Start from the very basics. Assume we know nothing :)
Please, please, pretty please add support for keyboards that aren't qwerty. There's so many developers that don't seem to know that WASD doesn't work for everyone. (hint: arrows as alternative works just fine)
The game needs a gold drop per enemy upgrade. As it is now, you grow stronger and stronger, making the gate break faster. And because of that, the gold gain per energy spent drops over time. Which is frustrating.
I like the game, but it's not playable on laptop without extra screen: I don't seem to find a way to scroll the screen up to see what the opponent's attacks are going to do and that is a crucial part of the gameplay. (the same happens with very tall opponents on a bigger screen).
Also, the full screen button doesn't seem to work.
Currently the best solution seems to be to zoom your browser out a step or two. I know it's not ideal.
You're in an iframe, so the full screen won't work, unfortunately.
The new assistant is a nice touch, but I have already used all available rubies and a hard reset to get it seems a bit extreme.
Also, I think 20 rubies is a very steep price for an automation.
When I click the chest at Bandit Raid, I often open up the pop-up for the quest instead. It would be nice if chests are always on top (for the click) so that you don't accidentally click what's beneath.
eh the game just crashed. I think I was near the end. The telephone was beaming in my reflection. I went back to the seasons menu and there it crashed.
Working on it, also improved tutorial a bit recently :)
