Quite a nice well-polished game, Awesome to play. The only thing that I felt was out of the line was the level design and the progression, it seems to be way off. The game progression in terms of difficulty is not linear and changes randomly which makes it harder to complete the starting level but easy to figure out the solution for the next one. Also, the level design could have been way better. You should be making the players immersed in your game first using some easy levels and then ramping up the difficulty slowly to test their skills.
Will be looking forward to your future projects for more such awesome content.
