Grasshopper4k
Nice cartoony graphics. This game is very similar to 4x4k. How do the physics work? Verlets? I can’t seem to beat the first level. It would be nice if flipping over just cost time rather than causing me to have to restart the level. Can’t there be a rotate button that just penalizes me with 10 additional seconds or something? There should be more to interact with than just hills. How about obstacles to jump over?
Run over Zombies is a really great and fun game. I’m really impressed by the 3D city, and that there’s actually animation. One thing I don’t like is that you can’t lose. Maybe add a time limit?
Honey4kKeeper
This is the second bee game in the contest. The graphics remind me of Atari 2600 games for some reason. Nice. You should have made the instructions clearer. The goal is to transfer honey from the hive to the pit in the lower-left corner. When you construct ladders, you should make them diagonal and walk up them Donkey Kong style. Each level seems very similar. Due to the way that bees move around, it’s almost impossible to use the cigar affectively. The hive grows way too quickly. When you drag to create a ladder, there needs to be some sort of visual feedback. I have to wait until I let go of the mouse button to see the ladder I created. The fact that you created auto-mode suggests that the difficulty of the game is too high. But, I have been playing with normal mode without a problem. I couldn’t beat level 3 because the hive grows too quickly. I like how the character gets all bloody as he gets stung. Interesting game concept, but it needs to be fleshed out more.
i4kopter
About 25 years ago, 3-2-1 Contact magazine used to have a section called BASIC Training that contained 1-2 page BASIC programs that you could type into your computer. The section was actually a continuation of a magazine called Enter, which only lasted for about 3 years. There once was a program in there very similar to this. The BASIC version didn’t support scrolling. The user controlled a tiny spaceship that slowly moved across the screen from left-to-right through a cave fully of jagged stalactites and stalagmites. Every time you tapped the spacebar, the spaceship gained a big of upward momentum. That game got me into programming and your implementation brought back some really cool memories. i4kopter is really primitive compared to other games in the competition. It’s also very difficult to avoid the obstacles.
Infinite Platformer 4K
Nice sprites, but you probably should have scaled them at least 4x bigger. This game does not offer a lot of depth as it is now. Instead of making it an infinite platformer, why not make stages 8–10 screens long? Generate some landscapes instead of just random platforms. When you jump on an enemy, you probably should bounce instead of just passing through them. The enemies could interact with the player a bit more.
Sea through
Very clever game idea and very impressive graphics. Please tell us how the physics behind this works. The screen is also very large. I wouldn’t expect this to work with such high resolution graphics. It’s a difficult game though. I can’t figure out how to reset after I accidentally crash. After I got the boat to the green square it did not advance to another level. How many levels are there?
Sea Spin
I like the plasma fractal generated land/seascape. It would be nice if the boat sprites, rocks and goals were larger. Controlling the speed of the boat would make the game easier. The game seems a tad repetitive.
QuadSquad4k
This game seems very buggy. My ship seems unaffected when it collides with quads. Why didn’t you create asteroid shaped objects? Why quads?! The game entered some sort of infinite loop where it kept resetting. How do I slow down my ship?
You seems like a curious little boy, who are always asking his parents. 
Collision detection scans every points of the ship whether is in any quad or not. Of course exact solution will be that scan points of the ship and scan points of quads. This latter examination is missing.
4k game 4 sides objects. The real reason is that I did not compress the jar file because I did not know some compression method. This is my first Java game and I tried to write a game without compressing.
Infinite loop? What kind of situation did you detect it?
Ship is easily decelerating. It has a velocity vector, just turn the nose of your ship against the vector and accelerate.
Just out of curiosity: you won all five levels using this strategy?
