Great game. The gameplay is fun the visuals are great as well :-)
I just wish there would be checkpoints, which when you die you can choose which checkpoint to start at :-) You could deduct the time based on the checkpoint you choose to start at to compensate.
Example if I have picked up 200 seconds worth of time, then when you have reached a checkpoint and die after. The player would maybe choose to start from that checkpoint, and you would deduct the seconds it took to get from the very start to the chosen checkpoint ( you can have the time it took saved somewhere ).
That way players wouldn't have to fight their way to get to the place they were at when they died. You would still have 200 seconds worth of time if you decide to spawn at the start spot again though, even after having chosen the checkpoint earlier. So the time would only get deducted temporarily (if that's the right word), based on the checkpoint you choose :-)
I hope I explained it well enough :-)
