pretty fun, I like the level design and the interaction to get into next level. some complaints though:
1. in first level, maybe add more virus at beginning, because at first there are so few and as a new player you get lost what should you expect to do
2. add more clear instruction about what is dangerous and what is not. maybe give all dangerous items a special color/border so it is clear those stuff you should avoid. Otherwise player might get hit something they think should be safe but die.
3. As a not expert player, I would hope to restart level not the whole if I die lol
4. the worm in the first level fliping sometimes and make it harder to avoid them.
But in general I like this game and idea and the art!
