This was a really fun concept that it is executed very cleanly! Drawing the triangle glyph was very satisfying to release the missles upon the enemies. The core concept is awesome and you should do a lot of playtesting to really hone-in and what is fun, but there's something good here :). Keep it up!
Other comments:
- The tutorial text shouldn't be in the background, i would move too fast to read it
- I didn't understand the time dodging aspect. I followed the instructions in the tutorial and time didn't slow down.
- Furthermore, I didn't really figure out how to properly dodge enemies.
- Make proper health bars for the UI, make the UI more intuitive. This video helped me out a lot: https://www.youtube.com/watch?v=sc3h5JXtIzw
- Scrolling is very smooth and helpful. Scroll out to see glyph design, scroll in to be more exact. Nice
- There should be smaller glyphs I should draw when enemies are attacking your base. A small loop to fire off 2-5 missles would be helpful, and the large triangle glyph for big missle attacks to keep enemies far away. You need a variety of both. I didn't have any good defense mechanism against my base when enemies would start attacking, it took too long to draw the triangle.
- The snail lore made me chuckle and helps outline what this game is about!
