Great idea ! Reminded me of those flash games I used to play when I was younger.
The first doorway is hard to go through even more since the fire is fast. I think you should add items or stuff you can buy with gold between runs.
Congrats !
Thanks for the feedback. We definitely will add items and powerups to buy between runs. It was actually planned, but not enough time to implement during the jam D: Also, tuning the difficult a bit more, to be more challenging as you progress.
