Every jumps require pixel perfect precision/timing and you must always jump when your body is totally (90%) outside the edge floating on nothing. Your 1 hour game can end at any time, you will loose 8 lives over a simple random jump after 45 minutes of play. Very frustrating game.

Also the game use the cheapest mechanic to make it artificially last longer, you only have 3 arrows and you must constantly  backtrack to get more arrows (because you cannot predict where the arrows will land).

Technically impressive but the DEV should read a book about game design 101.

PS : I completed the game.
