...926 seconds... can I win the "worst player of this game" prize? Man, my skills in platformers are abysmal XD
My obsessive self liked it though, enough for completing it rather than just give up... I think I spent about 100 seconds in the place where there is that one row of spike to drop-down in, then another 400 from last checkpoint to the end...
One of the things that helped was your background design. I realised that if I stopped in the middle of the darker squares I could "easily" squeeze in between spikes and not die. If one day you want to make a hell mode, make your background uniform XD Else, it was very good design on your part to help the player with such a simple thing (planned or not) :)
