I tried to complete this game. I really did. It's your first game, and the concept is pretty cool, but the execution is really flawed.
My biggest problem with this game is the gameplay. The controls are sometimes unresponsive and the hitboxes are unforgiving. While I like that the levels loop back on each other, as it creates for some interesting level design and gave places I'd already visited a new feel. However, with the hitboxes, I wasn't able to enjoy it. I recommend making the hitboxes a little smaller. Though it might feel wrong to you, to us it'll feel great, having that leeway.
Overall, you are a creator who shows promise. All the problems I have with this game simply seem to be the result of too much content. On your next game, try to focus more on the mechanics. Try less to make more levels and more to make higher quality levels. Try less to make make more parts that require a mechanic and try more to perfect the mechanic. I promise I much prefer a game with 1 level that feels great to play then a game with 100 levels that feels annoying. Please keep at it. I hope to see more from you!
