Omg, how much progress!
It was a while since I played the game and before I could do it I also accidentally started the first version (from the itch.io client), and now that I have tried 0.9.1 ... I am speechless.
There is still a lot of work to do, for example the possibility of mutating the audio, I almost became deaf.
But I owe you my warmest congratulations for the enormous improvements you have made to the project.
Starting from the most immediate as the UI, which you managed to create in the same style of the game, perhaps too simple but sufficient for this type of game (don't know, instead of the words some icon?)
The new enemy is now more within the reach of the player's attacks but still remains a killer with his lasers, although it is a pity that there is never more than one.
But most of all the biggest improvement is the rebound when you kill an enemy, the first time I discovered it was amazing. Since then I have continued to try to take more than one enemy at a time, risking more than once to die. But it was still fantastic.
A somewhat more elaborate menu and maybe a few more backgrounds would be nice additions, but I still think the game is really well done.
Congratulations and thank you for sharing it.
