It seems that I have a lot of criticisms for this game. It's very buggy, that's a first. The difficulty significantly decreases as the level progresses. There's no point in doing the night missions. Repeating levels shouldn't give full experience but experience of the level minus the experience previously earned.
This is one of the best educational games out there :) Clarification? This educational game has quality surpassing other educational games out there. Back up my statement? It's funny. Question relevance? It's in the comments section. At most times, the points to be made are obvious; it's just a matter of structuring your arguments in a communicable fashion. Right, Immanuel Kant?
Towers:
Bog- Bad Fog. Warlocks with rainbow easily counter.
Arrow- countered by shield golem + healer.
Holy- warlocks with rainbow easily counter, but easily countered even without rainbow.
Cannon- counters Turtle + Healer position, so take Golem + Turtle then healer position.
Rapid- counters Turtle. Easily countered by golem + turtle.
Crater- heal and golem work good.
Nuke- get elems for energy
Suggestions: Add more gates, doors and keys. Bosses are now confusing because of the repeated use of keys. Add a stop gravity. Stop gravities will stop all your speed and return to 0 speed. Add background blocks. Add a chatting system. Add a user name system. Add speed up gravities. This makes the your speed towards this gravity double when going outwards. Add magic blocks which disappear and reappear at certain intervals. Lots, lots more. If you agree, why not put a plus?
