1: Nice idea, i see a lot of potential in this game.
2: Some ideas for improvement:
Add to the upgrade system some upgrades that require other skills to be learned beforehand ( ex: skill c requires skill a and b ) its nothing original but it works.
resources are too easily acquired. instead of the energy crystals or whatever they are called, you may want to consider dropping the + energy from the crystal and having something such as - energy crystal " destroy it to receive 5 energy ( one time effect )
Increased difficulty.
3: Bugs i encountered. Just one, it was when i had a ship warp in it did not warp all the way on to the screen. I was still able to control it and after i moved it 1 time the problem fixed itself. so not really a big deal, but it was there.
Anyways for the moment thats all i can think of again good work on the original idea and good luck expanding it ^_^
well... every time i play this game it freezes after a battle on the point accumulation part. it always seems to only happen when i havnt saved for a while. ruins my day.
i dunno why everyone is crying about kreds. people just wanna make a little cash for their hard work. but either way i dont find this game very entertaining.
well... the challenge where i am supposed to dodge 5 bullets iin a row.... i did it...like 10 times. it wont give me the completion on it.. not ganna get the badge for that :(
