I played the web game on PC and it ran smoothly. It took me about 20 tries to successfully land for the first time—it's fairly challenging but still enjoyable. (I wasn't aware that the left and right arrow keys could be used for controls.) That said, I don't think it necessarily needs further expansion. I do wish the level selection and retry mechanics weren't quite so punishing.
There is a disabled abort system in the game. On an abort press the lander seperates and the capsule is launched up, if you clear the screen you get a free retry. I disabled it because in my own playtesting I thought it made things too easy. I'm considering enabling it before I wrap this up.
Thank you for taking the time to play it and the time to give me your thoughts on it. I appreciate it.
