Android users: ignore the permissions needed. I don't know why he asks for those permissions; I never use them and they're not included in my AndroidManifest. My manifest is as bare as it can be. If you know how or why, drop me a hint.
okay, well i played that for i'm pretty sure too long. i used my phone. bad: as it runs it progressively freezes up more and eventually crashes. this happened consistently. when dying and retrying the music often played over itself and sometimes the intro song would play too. good: the enemy types complemented eachother and it all fit together well game design wise. i had fun.
Good game, though I didn't get what the bar on the right means? As already said its probably more fun on the phone than on the PC (I played on PC) but I will mind that in my ratings ; )
I really like how the challenge scales over time, and the music :-). I think you could probably make a random scrolling background, using the same sprites you used for trees, rocks and lakes.
I played this on Android. I like the music and sound effects. :-) The gameplay seemed to be literally hit and miss - often I thought that I had hit a creature, only to die because I hit slightly too early or late. I like the presence of scoring - it gives a reason to replay, and to try to progress.
You have to wipe right in front of your unit to attack, not a perfect solution on tablets (I played it on a Nexus 7). Tapping/Wiping detection would be fine.
Its a complete game, nice :)
