I played your game, but it still has a lot of things to keep working on.
Here is a list, if you are interested:
- Is the game really created in 7 days?
- Enemies are only at start, but are not spawning and there is no end... (the game is really short)
- Enemies seems strong, before you start moving then they are easy to kill (balance enemies)
- EDIT: Limitation is "Player must cheat", cosmic is optional theme, but don't worry, mistakes happen
I liked the menu UI, good luck in game development.
