This is so haaaard :'D
I see a lot of other people have mentionned the controls, and yeah they're super rigid and unusual, but as someone else said it gives a kind of unique feel to the game \o/ The downside for me is that it means that it's a bit long to reach the place you just died (but maybe I died more than the average!). I would love an easy mode with pretty close checkpoints :p
Anyway, congrats for your very first game, it's super cool!
