+* [colin] parfois je dois appuyer plusieurs fois sur "Start a new run" pour vraiment commencer une nouvelle partie. dans ce cas, lhécran de jeu derrière se "désassombrit" comme si le jeu avait démarré plusieurs parties en même temps.
+* [colin] lorsque le puck est trop petit, l'affichage du combo disparaît. mais c'est peut-être volontaire pour qu'il ne dépasse pas du puck ? afficher simplement le chiffre serait suffisant et tiendrait dans le puck
+* [colin] le niveau bug parfois et ne peux pas démarrer. dans ce cas, la balle apparait comme démarrant sans être attachée au puck, comme si la partie avait déjà commencée. il faut redémarrer B71 pour que ça fonctionne

 - the onboarding feels weird, missing a tutorial
 - It's a bit confusing at first to grasp that one upgrade is applied randomly at the start of the game
 - on mobile, add an element that feels like it can be "grabbed" and make it shine while writing "Push here to play"
