Thank you for your insight.
It is true that this version is a tad too penalising, but that has been fixed and balanced in the latest version.
The idea of it being having one type of mode is a bullet hell endless mode where you have to get as far as possible battling the time gained from the kills against the diminishing energy of the reactor.
There are other modes planned as well and I will be taking in suggestions and critique so I can deliver a more tuned up game for most of the audience.
