I found this game quite enjoyable along with being unique in concept and nice in graphics and gameplay. I would buy a full version and I wish there was more to play. I did get 1250 gems at the last level by killing all the waves and not killing the boss, hoped the enemies would keep coming and I could buy infinite upgrades. If you do continue this game I think a endless mode would be a good feature along with a continued level system, or just a endless mode.
Hey SaferAce, thanks a lot for leaving such cool feedback! Those enemies should be spawning infinitely, but unfortunately, I've never found on the code why they suddenly stop spawning hahaha.
An endless mode is a super cool idea, it's amazing to keep adding upgrades until the tower is completely broken and amazing. Since we are planning a full-fleshed game, an endless mode will be considered for sure!
