I'd like to commend this one. It looks very well put together and functioning.
I'd like the checkpoints to be actual check points.
I'd enjoy the game more if death didn't end the game outright. Also as a Doomslayer if you put a bomb near an enemy and then cross a checkpoint before it dies it subtracts a star. I know its obvious, but you made the controls so good I just want to be running arounds headlessly placing bombs everywhere.
Which neatly brings me to another point. Why just 50 bombs? If you had a certain ammout per room (before checkpoint) I would kinda understand it but 50 just sounds very random. I haven't been able to finish the game (cause I was running as a luntaic placing bombs everwhere) so I don't know if the limit of 50 means you cannot waste one but that sounds like a challenge run mechanic and not a base game one.
Overall I really like how the design fits together. It controls well. So overall very happy.
