A concept that have been seen but really well made with nice little touch/polish.
I just felt like the jump was not forgiving enough, like, the spikes line were a bit too long, maybe that's wanted and you want the puzzle AND the platform type, so in this case, that's all good.
Same for the ennemy, the jump on there head was a bit unforgiven. But well, you can't extra polish everything with so much little time. But I read that you may do an update so just telling what I'd want to be changed :).
It's a great game whatever!
