Glad you like it!
At the moment, I'm focused mainly on the next two releases.
v0.8 (~June): Conclusion to the current story arc (Act 2). Significant additions and improvements to the training system, such as the ability to finally level up. Other minor improvements if time is available.
v0.9 (~August): Coincides with the Steam release. First hour or two of Act 3. Gallery mode is added, along with any remaining player suggestions on my to-do list.
