Solid idea for a puzzle game and I REALLY dig the music.
The visuals however, are… a bit jarring. The spikes are really cool and detailed but every other stage piece is a gray block. If the spikes, the balloon and the skybox also used simple models, flat textures and similar shading the game would look a lot more visually consistent. The spikes unfortunately end up being a case of more is less.
Also maybe it’s only an issue for me but when the game loads initially, only a quarter of the screen is visible and the mouse is displaced. When I locate the fullscreen button by clicking around and then going back, the screen size gets fixed. This didn’t actually prevent me from playing the game when I figured out the fix so I am not really judging based on that.
