Hey there!
First of all, congrats on making the game and sending it here, really glad you made it! However, I think need some improvements here and there. I saw your comment saying that we need to press G in order to enter the level/tutorial. But it would have been awesome to have a tutorial directly into the game, as some players might leave after seeing the game is not working. You also need to fix the bug where you can fly, because what's the point if I fly over the map to the finish, right?
Nonetheless, the game shows the amount of work you put into it and it's great! You did very well, keep improving and learning. The review was a honest and constructive feedback and I hope you will be able to learn from it. Great work!
I would love to have you playing mine too, if you don't mind of course! ^_^
