I personally enjoyed this game a lot! Maybe I would have fixed the collisions and I would have awarded the player for creative techniques (like bouncing at a wall full force to jump at an angle). Overall, it was a great game to play! :)
Thank you for playing! Originally the collisions did have more bounce to it, however for long jumps it tended to cause player to bounce much further than the rose platform, so I opted for less bounce to give the player some leniency. However like you mention, it would be cool to ricochet yourself upwards.
