The first 7 waves are very easy, so it's definitely more of a game that tests endurance and patience, rather than outright skill. From 8th or 9th wave onward you start to lose lives, since you can't realistically make it from one end to another in time. At the start I wondered what the jump could be for, but I noticed you can get the coins faster by jumping to get them. It's a cool game with the minimal colour palette and nice music.
I'd like to invite your game to our game-making contest, we also have a class for jam entries!
