That was one of the best pieces of feedback I've ever received for this game. Thank you so much for taking the time to write it.
-The Falling Swords description has been changed.
-Right click has been added as an alternative to the Space key. It does the same thing.
-Regarding the progression, I completely understand the issue where you can finish one level and then fail to defeat even a single enemy in the next level before the loop ends.
To address this, I added a skill that isn't available in the demo. At the start of each loop, the first certain number of attacks don't consume stamina. For example, the first 50 attacks won't reduce your stamina. I'm hoping this will solve the problem.
I'm also going through every level one by one and carefully adjusting how much stamina damage enemies deal to find the best possible balance.
Once again, thank you so much for the great feedback. It really helps a lot.
One last thing to keep in mind: I don't plan to update the web version anymore. The Steam version will always be the most up to date version of the game.
