I so badly want to be Hot Dog's pal, but I wasn't able to survive long enough. The jump height seems to be pretty random, when I hold down Space I seem to jump somewhere between 2 and 4 tiles, but sometimes much higher. I like the look, but I found it hard to see projectiles and platforms against the noisy green background on Forbidulon Prime. My main difficulty was that I don't have the dexterity (or, with my left hand, sinisterity) to handle directions and jumping with one hand on the keyboard while shooting with the mouse in the other hand. A few hits starts the whole level over, including a long conversation, so I quickly got fed up. A shame because I really like what I see, I'd have liked to have gotten to the gravity mechanics I see others mention.
