First of all: You probably noticed that the full game hasn't been released yet. The reason I had to postpone is that I'm still not completely satisfied with the current state. I think there is still room for new levels, fun game mechanics and better graphics, sound effects and animations. You deserve a polished game that provides a fun and challenging experience! In the meantime, I'm trying to continuously upload new demo versions. These should provide a vertical slice of what the final game will have to offer. I see it as a way of providing early access builds, completely free of charge. If you give me feedback in the Steam Forums, I will do my best to improve the game. Here is a list of highlights since the last release:

• Added cannons and bullets (this should make differentiating between opening and closing barriers easier)
• Added new static level elements for decoration and fun
• Improved barrier logic (fixes a bug where a player would get stuck in the gate)
• Improved level selection menu and other UI aspects
• Updated demo levels (currently includes 10 levels)
• Added support for Steam Input API (with controller glyphs and everything)
• Added support for Auto Steam Cloud (so your progress is synchronized across devices)
• Initial support for achievements and leaderboards (not included in the demo)
