9/1 Update — Demon Strikes Back Steam update #1090100

New Feature We have implmented a new way of how skills are upgraded in game. Now skills can be upgraded at the end of every level (with a cost), with a new UI showing you all potential upgrades. So you can better plan your build. The old skill upgrade altars are changed to a more rare appearance, where you can get a skill upgrade for free. Improvements: We have made some changes to sound effects of sword weapons. We have implemented a new rendering path for visual effect when hitting enemies. Bug fixes: Fixed an issue causing a few enemy skills not able to hit player. Fixed the confirmation window display when purchasing items. Demon's sprint skill can now change direction while running.
