Graphics are nice and controls are fine apart from few small gripes.
Games with such precise jumps should check if the button is pressed again after landing, as now you can accidentally jump just after touching the ground.
One block wide holes are a bit too precise to jump through at a fast pace and the lava pits kill you on contact, so you need to time your jumps differently from other similar jumps in the game.
None of these are a deal breaker, but finally the game decided to throw me out of bounds and as the game has no level reset button, had to wait until time ran out, but was still stuck.
The bug has been fixed, so you can finish the game now.
