I revisited this and now played all available levels. Here some additional findings:
What I like
- The graphics style
- The user interface is intuitive and easy to learn
- Game pacing is well done, I play all the time as 1x and it is flowing well
Things that could be improved
- Add more variation to the levels:
- There is no much difference if you have to send 4 or 10 bunnies to space
- The rocket is rather cheap, I was able to build and launch it always on the 2nd day
- Maybe add upgrades to the rocket: Level 1 has only 4 seats, upgrade for additional seats
- I had no need for the different tower types, maybe add more versatile enemies that require certain towers to counter
Issues I encountered
- Once I was stuck in the night, speed was at 4x and nothing happened. I had to leave and load again to make it continue
- When choosing the tower type it is not checked that there is enough wood, I got negative wood once
- Upgrades sometimes seem to be stuck, then suddenly they have very fast progression
