So I got the game to work somehow and now I can give a review:
Things I liked:
- Simplistic style
- Can be picked up rather easily
- Good transitions
- Loading times are good
- RNG of getting turrets and buffs is fun
Things that I didn't like:
- Zooming is not very good
- No sound, it makes the game feel a bit empty
- UI doesnt make a lot of sense when first looking at it
- Any TD needs the ability to speed up so you don't have to wait for money and also a pause
- UI should not move along with the game when zooming
- Not very clear originally what turrets do
- When selecting a turret, the only way to close it is by clicking on an empty turret slot, this is not possible once you are filled with turrets
Conclusion: The game is very simple and it's hard to do a tower defense wrong and this ones not that bad. Good luck with your development and I hope you can improve on your game in the future!
