Great classic game
It's a great game, it's balanced and fun to play.
Tactics are... Mwah ok. You can use them, or go "omg rush"
Regarding poison: ALL poison is leathal, since it blocks healing. Only the black scorpids' poison is weak. the poison from the green spiders/scorpions does 60 damage per turn for 10 turn = 600 hp gone + no healing = sure death for any spider/scorp. So make it last 1-2 rounds, cept with the spiders that have "leathal poison"in their tooltip.
Extra things, like being the scorpions are also fun to have.
Also, the black widow tooltip says it cant attack the same target more than once, but it does anyway, same with the black scorpid.
The graphics are good, and you can turn of the sound / music ^^;
Gameplay is great, just a tad unbalanced.
I enjoy these games you make, and I hope to see improvements in this one ^^;
You could even make this into a real game! (just not yet T_T free games ftw, even more so if they are as well made as these ^^;)
Keep up the good work, and try to get to these "bugs" and "glitches".
