Super old reply but I haven't been around itch.io in a long time. Thanks a lot, I'm glad you had fun with it!
And just saw this now. In case you'd still like to know: this was done with construct 2 which creates a html5 game. sadly I can't just create an executable windows file with this software (as far as I know. might have changed now. Construct 3 has been around for a while now which I haven't looked at)
