Thank's a lot to everyone for testing and your advices. ^_^
@hare-software ; @dane-tesla The level needs more playtest for a real challenge flow and keep the player. We should focus on fewer things next time. Absolutely, the rendering contrasts with the rest. We missed time to work on a better UI.
@sergio1811 That is the result of several iterations around the theme. At first, we started with a player who was moving on a map with only an exit door. And to reach the exit door, the player can jump. The jump action creates a platform for each jump made. But we realized that the player ended up getting stuck with the accumulation of platforms. The inertia of the runner made the experience fun but too difficult to master. So we take the decision to create and control only the platforms. I hope you better understand our decision with the theme. And Yes, good idea ! I think it is possible to adapt the mechanics for mobile to make the concept more interesting.
