You say that this game is not good, but I honestly think that if you kept developing this it could be a really good rocket puzzle game!
Firstly I really enjoyed trying out different combinations and trying to get as high as I could, and although I couldn't get up there I kept thinking 'but which bit is right'. So, maybe try and remodel it as a mastermind based game where instead of just saying 'You failed' say '2 of your components were right, but 3 were wrong try remodeling?' and then it would end up being quite challening!
I loved the idea of picking your launch site! I kept seeing if placing my rocket on the highest mountains was gonna work, but maybe a little flag in the background/ a change of background (which you could split up into map strips) would just add that extra edge!
Overall however, I enjoyed playing this! I think if you were to keep developing this it could be really really good! Well done!
