Thanks , ye a few ppl have said anteater. I never played it before though.
Aso for the rewind thing, theres tsill room for some button optimizations (mabie hold to wind or some kinda input delay if your at the tape to stop it switching asmuch), it was initally the way you said but I didint think it flowed well and we may have plans to use that button in the future for something else :)
There are only 15 levels in the demo so u must have got prity close.
