Hey just tried it, pretty fun, think it would be good as it expands on like Android, or iOS as I played with a touch screen and it worked really well! Maybe an on screen hitpoints counter alongside the screen dimming would be good, and yeah 'more' of everything like enemies, powerups etc as you say but enjoyed it, well done!
Thank you very much for your feedback !
Firstly, I don't really think I will expand it to mobile, even if it works, but maybe one day...
And also I know there is not so much content right now, mainly because it was my first game in Godot, so I made this to learn about it and I actually leart. I don't know if there will be updates, because I would prefer to work on other games if I get some ideas, but if I have some time why not ?
