Desperate Defender

not very hard. I had all upgrades by round 12, and even by round five or so i could easily win by merely holding space and a directional arrow. This quickly made it boring, as it didn't even feel like there was any gameplay involved. The fact that, since one must destroy all enemies to complete the round, there is a set amount of gold earned, means that unless the player plays stupidly enough to have to heavily invest on repairs, the game is essentially finished quite quickly. More upgrade options, or buildings, as was suggested, would make this game much better. 3/5, since 2.7/5 doesn't exist.

blending issues on lvl.3

you dont need the logo up there for that long

After obtaining almost all upgrades (around level 8), it's just a matter of rotating around the planet continuously and shooting. Otherwise: fun :)

Very cool game it does feel like it needs a little more i would suggest more types of weapons maybe like different kinds to branch off of like speed power and spread or something. I would also like to see maybe some building and you would be defending a civilization you are trying to establish on the planet and have to deterimine if you need to construct buildings or make more weapons. Alot of potential so i'll give it a 5/5. Keep working and it can be great.
