What is this control scheme?! Mouse and up arrow for jumping? It's especially hard since for some reason my screen keeps scrolling up whenever I press the up arrow. I don't know if that's due to the game's programming or if it's just the computer. It's an annoying control scheme, to say the least. I have to use the mouse with my left hand while using the arrows with the right. This is inconvenient for someone who is right handed, as WASD would have been much more intuitive. Perhaps add an option to configure the controls manually. The graphics are also just reused images. There's no sound. I appreciate the bonus level, but... why is it unbeatable? In fact, the second level is also buggy, which you even say in your description. The gameplay is boring and the physics are nonsensical. In most games, you would achieve the highest possible jump by double-jumping when the first jump is at its highest, not when it's at its lowest. I guess it's because of momentum carrying over, but this needs to be fixed. This game is barely playable and boring. I hope that with these suggestions, your next game will be better.
