Good alpha. Fun to play!
I liked the art style and the music is great :)
- As already mentioned, it would be nice to have some indication about enemy health and when hit
- Maybe stop spawning enemies in each area after a certain amount to give a sense of achievement
- Check point could be materialized with a flag, for example, or each door could be a check point
- I couldn't find how to open the door that lead to a room with blinking magenta squares...
- Would be nice to loot from enemies (health, new weapons...)
- Need some indication about the player's health!
- Could add a dash with space bar to dodge enemies
Well done!
