Great design !!! it got the feedback sound too when getting damage or upgrades. The UI in game is great and clear.
Negatives points :
- the gameplay depends too much on upgrades, especially multi-shot upgrade (It's op lol; 1st no orange upgrade = too many enemies at one, quite hard / 2nd game = 1 orange upgrade, the game became too easy but it was fun)
- too short (with upgrade lol)
- no "exit" button in the main menu and end screens break the immersion (and it's a bit cringe...)
Fun game and great design. 9/10
