upgrades are missing, with upgrades the game would be less boring

mhm

that was stupid.

It was ok. Nothing special. But it is addicting.

More work

not a bad start at all, but like the other reviews say, more enimies, upgrades and such. Just keep up the work.

A little boring

Unfortunatly, this would not be something i could get into. Streight random waves of baddies, no upgrades or invreasing diffaculties. The aiming was off and the baddies were glitchie.
Really what it comes down to is that this is a decent start to what could be a good defense game but I would advise to do a little more research on these types of games or just out right spend a bit more time on this in general.
Keep working on it and dont get discouraged.
