I just completed your Dasher game. I like how you've given the character a double jump and a wall jump with the added ability of sliding up the walls too, that's awesome! Level layout is great, the springs work well with the character's ability, sound and colours are great too. I like that you've got a level select screen but once you've completed a level and you click play on a certain part of the button it can click through to the level select screen and into a level you don't want to go to. To solve this problem, I would recommend setting the button to On Left Mouse Button Released, rather than pressed. The spikes are really cool and are well placed but I think if they were resized, they would fit on the platforms better and it would look a lot nicer with things aligning up. Overall, it's been fun playing your game and I hope this feedback helps with the development, keep up the great work!
