I don't even know what to say, even though it was made within a week, this game is nearly perfect and I loved it a lot!
For feedback purposes, the minor issues I found were:
- Without a tutorial, it was kinda hard to fully understand the game in my first playthrough (for instance, I didn't knew I could hold the shoot button nor that the map indicated where immeadiate attention was required).
- The shop could have purchase confirm buttons and make it clearer that you can't use two upgrades of the same type at the same time.
- Difficulty starts hard but gets easier as the game progresses.
- If you lose and try to play again, the game behaves weirdly.
- If you beat the game and quit it, the game shows the game over message.
This is me beating the game after destroying over 4000 enemies, thank you for the fun I had! :D
