Thank you for your play and such detailed comment!!
About the ashes lasting time, I would try to find way to make it longer, the algrithm for now is just instantiating them under the fire (which takes more memory), may be I sould try particle system.
About the enemies, thank you for pointing out, we actually didnt pay enough attention to design the way they interact with the environment, the hit and eliminate way is just too basic, maybe adding some gates or barriars that could be triggered to block them? Or making the ashes ‘toxic’ and staying on it for too long would light the enemy? I would think about it.
And, I think I should label it, the reset actually would not reset the enemies but the explosion bubbles and player energy. This is because the final goal would record the time you spend to reach the end no matter how many times reset, so the more player is familar with the map, the less time he/she would spent. Also, the level might be a little bit hard with enemies respawn. Since you consider it a bug, I would reconsider it and try to make some modification. ( If you mean the reset after reaching goal, I truely didnt make that)
Appreciated for the long comment and those suggestions!
