Pretty cool game! I took me some tries to beat the 700, but I did it! (I played the v2 version)
The game is already fun, and feels complete.
Things you may consider:
- Furter improve the controls, sometimes it is hard to hit an exact spot
- The maze goes rather quickly from super easy (~800) to impossible (~1000). Maybe you could ease that out a bit. One idea could be to allow infite bombs, but make them more expensive every time (maybe -10, -20, -30, ...).
- You could change the algorithm so that at some point the maze gets more complicated, but does not block completety: Not only add walls but also remove others, so that the path to the exit becomes longer but still exists. (I am aware that this may be very difficult.)
