Having played enough of this, I can confidently say no one will "contribute to its evolution" on account of a complete lack of compelling features. It's not fun at all.

* Movement and aiming feel terrible.

* Enemies have no diversity outside of moving and shooting.

* Special attacks on both ships were bare improvements over basic weapons.

* Bumping into enemies for damage does not have balanced risk/reward and take out a lot of health.

What is effectively Galaga + physics is a very weak premise. I think the developers should call it a day and move onto a new project. Credit where it's due, they released it and that is a genuinely commendable achievement. I hope they continue to grow and release more games.

A word of advice to the developers: if the most basic prototype is not impactful and you can't make it impactful in 2 weeks time, bin it.
