The Playermodel, tanks and all other interactive objects are good to very good (I like espacially how the rockets are flying
). The buildings need more details or textures with higher resolution. Or when I destroy the walls of a level of a building something interesting could be behind it like people taking a shower or something. There should be a big explosion when a level is destroyed (with soundeffekt). Otherwise itīs hard to say if itīs done or not.
The game plays much too slow. I know rampage world tour and I know itīs the same slow. But in your game everything is more huge but the buildings are repetetive so I recomment a faster gameplay. Faster to destroy buildings and maybe faster movement (walking). Jumping sometimes didnt worked. I had to climb somewhere before I could jump again.
A story line is missing. Because the levels are repetetive (got until the level with the choppers, there I died) a story would be something to know why I am still playing it. Story could be told between the levels by some 2D drawings or something. I mean I did ask myself where that monster dude came from or where this is supposed to end.
More weapons needed to destroy buildings faster. The buildings should break with less attacks. Maybe Climbing up and down could be faster too. And maybe you could add explosive barrels or tanks to throw at a building to destroy it complete on the first stroke. Would at more fun for sure.
Some objectives per level would make them less repetetive. For example destroy building A which is heavy protected by hard tanks (so I have to take out the heavy tanks first). Or eat 10 people at the marked place. Marked place is heavy protected aswell. Or find person xxx in house C (house is of course marked, but I donīt know in which floor she is). pick up person xvca and bring her to skyscrapper bda... and so on.
